The Mercury image
Ida's classes in the mid-1970s were filled with students who had grown up after the Mercury image had faded from American visual culture. When she invoked it, she had to acknowledge that the picture no longer landed for everyone in the room. The telephone book had once carried, on its cover, a figure of the messenger god standing on a globe — toes down, outer arch up, small wings affixed not to the back of his shoulders but to the outer side of his heels. Her students born in the 1950s might have to be told. The earlier generation of practitioners simply remembered. In a public-tape exchange where a student is pressing her to explain what the outer arch actually does, Ida walks the picture out of memory and into the room.
"The ten year ago generation, every telephone book had a picture of Mercury standing on a globe up on his toes with the outer arch up all That's where the wings were. That's where the wings were. That's as well. Now all these Mercury's that go way way back to early times, not primitive times, they all had the wings on the outer arch there. Meaning, because this was the way the old classicists thought. Mercury is the principle of transportation. If you are going to get around, you must act as though there were wings on that outer arch and you will get around."
Ida, mid-1970s public class, working through the second-hour goal with a student:
What she is doing in this passage is not antiquarian. The Mercury figure is shorthand for a structural claim she will defend repeatedly in the second hour: that the foot is organized from its lateral side, that weight bearing properly travels along the outside, and that the inner arch is the consequence — not the cause — of correct lateral support. She returns to the same image a few minutes later, this time with the Greeks themselves rather than the telephone book, and pushes the claim harder: the principle of transportation, of getting around fast and satisfactorily, lives on the outside of the foot.
"The Greeks, when they wanted to represent the principle of transportation, the principle of getting around, represented a young man with wings on the side, outside of his heels. They were saying, not that they thought that was a god that came around with wings on the side of his feet at all. They were saying that the principle of transportation, of getting around of getting around fast and satisfactorily consisted in walking as though you had wings on the side of your feet."
Ida, RolfB2 public tape, returning to the Mercury image from the Greek side:
Two arches, two colors, one rule
The Mercury image is the picture. The anatomy book in front of her in the same lecture is the diagram. Ida is holding open a teaching atlas in which the muscles attached to the three inner toes are drawn in one color and the muscles attached to the two outer toes in another. The two systems are stacked: outer-arch system underneath, inner-arch system on top. From this stacking she derives the rule that organizes the entire second hour. Lift the bottom layer and the top layer comes with it. Lift the top layer and you have destroyed the structure you were trying to build.
"The one color is attached to the three inner toes. The other color is attached to the two outer toes. The yellow sits on top of the gray. Now get reality on this. If you can lift the gray, you've got it made. If you lift the yellow, you've thrown it away. If lift on the inner arch, you've thrown it away. If you lift on the outer arch, you've got it made. It's that simple. Only some of you that were working didn't find it simple. Even the ancients knew this. Why I have the nerve to put in even, I don't know. The ancients knew this."
Ida, holding open the anatomy atlas:
The simplicity is misleading. Ida is not saying that the inner arch is unimportant; she is saying it is consequent. The outer arch is the structural floor on which the inner arch can rise. Where the outer arch has dropped — where the lateral side of the foot has collapsed to the ground and the foot has rolled inward into eversion — there is no platform from which the inner arch can lift. The orthodoxy of her century had the cause-and-effect backwards. Trying to raise an inner arch directly was, in her image, trying to lift the yellow layer without first lifting the gray. The passage immediately following the two-color rule turns into a direct attack on that orthodoxy.
"Is the mechanics of the weight bearing of carrying the weight along the outside arch first and then transporting it across the No. Weight goes on the outer arch. And all that you ever learned about taking these kids who have flat feet and walking around boards like that is the diametrical opposite of the therapeutic truth. No foot has ever broken down until the outer arch breaks down. While the outer arch is intact, the foot is intact. So all that you are doing, everything that you are doing with a foot in the second hour concerns that organization."
Ida, on what every flat-foot therapy of her century got wrong:
Aristotle and the inclined board
The polemic against inclined-board therapy has a philosophical genealogy in Ida's account. The orthopedic profession of her century, she suggests, was raised on Aristotelian cause-and-effect: identify the effect (a fallen inner arch), produce the cause (lift the inner arch), and the problem is solved. But the foot does not work that way. The visible effect — a fallen inner arch — is downstream of a different cause: the collapse of the outer arch, which is itself downstream of disorganized musculature in the shins. To attack the visible effect directly is to confirm and deepen the pattern. The passage where Ida names the Aristotelian error sits at the hinge of her second-hour teaching.
"Let always letting the outside of your foot go down. Now you see what was happening was that these boys were brought up with Aristotle. For every cause, there is an effect. And, of course, you can look at the effect. And the effect is that if you wanna get the the inner arch up, you lift the inner arch. You don't. You lift the outer arch. This is one of the things that this second hour is about."
Ida, on the Aristotelian inversion of the inner-arch therapies:
Where the actual cause lives, in her teaching, is not in the foot at all. It is in the shins — in the relationship of tibialis anterior, the peroneal group, and the deeper flexors and extensors that cross the ankle and shape the foot from above. Flat feet, she says repeatedly, are not in the feet. The structural work of the second hour is therefore not principally on the sole of the foot or the inner arch but on the leg above the ankle, where the muscles that govern the foot's bony arrangement actually live. This is the practical instruction that follows the philosophical correction.
"And with too many children, not enough other things happen. And flat feet are not in the feet. Flat feet are in the shins. They are where and how the muscles of the shins relate. And the place to go for your flat feet is not into the feet, but into the shins. And there, you organize the muscles that control the feet. Now what are you trying to do there, and what is your goal? And your goal is to establish an angle which acts as though it were horizontal."
Ida, the same lecture, locating flat feet above the ankle:
Pulley action and the woven foot
Beneath the polemic about inner versus outer arches sits a more careful anatomical picture, and Ida turns to it in the same RolfA1 lecture. The foot is not a stack of arches; it is a webbing. The peroneus longus crosses the sole from the lateral side, and the tibialis anterior crosses from the medial side at the dorsum; together they form a pulley around the underside of the foot. The arch is not a passive curve in bone but the active expression of this pulley. If the webbing is interfered with — if the retinaculum binding the tendons is too short, if the fascia has stuck the peroneals together, if the plantar binding is contracted on one side — the pulley cannot work and the arch cannot be expressed.
"The peroneus longus coming across the foot this way and the extensor coming this way. As you can see You see that forms the arch. You have a pulley action between the two. Where's the origin of the dorsal tendon? On the front of the foot, on the front of the leg. Right here? Yeah, between the tibia and the tibialis anterior. The extensor of the great toe and the common extensor of other toes. And then you see down on the bottom of all this you have the plantar fascia holding this binding it in."
Ida, walking the anatomy book with a student named Dr. Roth in the room:
From this pulley picture follows a different conception of what the practitioner is doing during the second hour. The work is not principally to push the outer arch up from below — that would be treating the foot the way the inclined-board therapists treated the inner arch. The work is to free the tendons of their fascial gluing, to separate the two peroneals where they have stuck together, to clear the retinaculum across the front of the ankle, and to allow the pulley to operate. The arch lifts as a consequence of restored sliding, not as a product of direct mechanical lift.
"Often times you have to go underneath the malleus to work on the two ligaments that are underneath, that may be displaced displaced and this sort of thing. They are often misplaced, but the ordinary aberration is the gluing together of the two peroneals. Right. And what you wanna do is to separate them so that they can each operate independently. Mhmm. Then you after you cleaned off the the malai Malaiola.
Ida, on the peroneals and what the practitioner is actually freeing:
The dropped fibula and the wedge of the talus
The outer arch is not only a function of soft tissue. It also depends on the bony positions above it — and Ida is specific about which ones. The fibula, the lateral leg bone, is among the most vulnerable structures in the body, and when it drops distally toward the floor or migrates posteriorly behind the tibia, the lateral support for the foot loses its anchor. A dropped fibula means a dropped outer arch. Conversely, the outer arch cannot rise unless the fibula is in a position to support it. In her 1973 Big Sur class she walks this circuit explicitly with the students.
"Well, this is true, but on the other hand, they've gone to realize that they have to establish the arts and then if you live on those sexual problems, you're quite right, but I'd be aware of the fact that you can't get the arch without the fibula. You can't support the fibula without the arch. Now when the fibula drops, the weight seemingly goes to the outside. Now whatever goes wrong with knees displaces the fibula. I mean every time it gets closer to knees displaces that fibula."
Ida, Big Sur 1973, on the reciprocity of fibula and outer arch:
By 1975 in the Boulder teachers' class she has a more refined mechanism: the talus, the small wedge-shaped bone between the foot and the ankle, can be moved by appropriate demand for movement in such a way that it acts like a wedge splitting wood — opening the structures around it and freeing both fluid flow and motion. The talus is, she says, one of the most natural wedges in the body, and it also functions as a spacer. The practitioner who understands this can use the toes-up, foot-up movement not as an arbitrary exercise but as a call for the talus to do its wedging.
"So what that does is it if you look at it, it a wedge. Right. Just like instead of chopping wood, you can put a wedge in there and hit the wedge and split the wood. That's hard to understand. And if you call for the appropriate movement, the talus acts as a wedge and opens up the structures more. That I just Which is gonna give you a freer flow of movement and fluids all at once. And as all those structures shift, then you move everything to where you want it. Alright. And it's one of the more natural most natural wedges of the body. And it also acts as a spacer."
Ida and a student, 1975 Boulder, on the talus as wedge:
Hinges across the dorsum
In the second-hour teaching, Ida names not one but two horizontal hinges that must be established in the foot-and-ankle complex. The familiar one is at the ankle proper — the joint between tibia, fibula, and talus that allows dorsiflexion and plantarflexion. The less familiar one — the one she insists most of her students have never considered — is across the dorsum of the foot, where the metatarsals meet the tarsals. Without that second hinge, the foot can still walk, but it walks around the joint rather than through it, and the outer arch cannot find its lift. The first hinge is given by anatomy; the second has to be made.
"But across the dorsum of the foot, there has to be, for normal literally a hinge joint. When that hinge is in then you can get the lift on the outside of the foot. Until that hinge is in you can cannot really get the lift on the outside of the foot. And as long as the outside of the foot is down, as you see, it is as we look at the normal accidental business of growing up and walking on the side of your feet the other day, as long as that outside is down, that door that hinge on the foot cannot operate. But that foot is just like any other part of the body. In fact, in certain respects, it's more complicated than any other part of the body. How many bones in a foot? 50 odd pounds. Two for the two of them. I don't know. I keep forgetting about numbers."
Ida, RolfB2 public tape, on the two hinges of the foot:
The hinge across the dorsum is something the practitioner brings into being through movement work — the toes-up, foot-up demand that Ida discusses in the 1975 Boulder teachers' class. The instruction is not a rote exercise. It is calibrated to the body in front of the practitioner: very high arches are not asked to bring toes up, because the call would only deepen the pre-existing pattern. Flat feet, by contrast, are asked emphatically for the toes-up movement because that is what calls the outer arch toward elevation. The discussion among Ida, Michael Salveson, and others in the 1975 Boulder class is unusually granular about how the movement instruction actually couples to the outer arch.
"Yeah, another thing that would change it would be the arch. For example, a person with a very high arch, wouldn't have them bring their toes up. You wouldn't have them do a toes up foot up because bringing the toes up simply creates an even higher arch and that would add to their problems, would think. And that's in that foot pain book too. Or as a person with flat feet, you really emphasize the toes that put up, would think. And I have to agree with that. Yeah, but sometimes when you're working their feet, get a normalization. You do like almost the same thing but the foot will normalize."
Ida and Michael Salveson, 1975 Boulder, on calibrating the toes-up call:
The center line and the unifying body
By 1976 in the Boulder advanced class, Ida is connecting the outer-arch teaching to a larger claim about the body's center line. The reason weight on the outer arch matters is not just that the foot collapses without it — it is that weight on the outer arch destroys the body's unity. The center line of the body, in her account, runs down the inside of the leg and finds the ground through the inner three toes only after the outer arch has provided the lateral support. When weight falls on the outer arch in standing, the center line is lost. When the outer arch is up and the weight has migrated back toward the inner three toes, the center line is recovered. This is the synthesis Ida is offering her late-career students.
"Get yourself comfortable and feel where you are in that body. You don't accept your head as being you. Seal at centerline if you can that Ruth was looking for. And where does it have to run? Now let your weight go over to your outer arches. What happens? You lose your line. Yeah. It's called you're no longer a unit. You feel it? Yeah. Anyone want to argue it? Now when you try to teach me about my business and tell me that weight should go down on the three center toes, Feel what the experimental data is behind that statement. Your center line connects down the inside of the leg. Your center line is destroyed as weight goes on to the outer arch. Now just turn your toes up and see how that begins to put the weight back again into the center line. See what you begin to feel as you begin to feel the establishment of that center line."
Ida, 1976 Boulder advanced class, on the center line and the outer arch:
This synthesis lets Ida deal with the recurring confusion in her advanced classes — students who have read in her lectures or in the 1977 book that weight is supposed to go through the three center toes, and who then conclude, mistakenly, that the inner side of the foot is the operative one. The synthesis is not a contradiction. The three-center-toes statement is, she says, the abstraction; the outer-arch instruction is the silent-level reality that makes the abstraction work. Both are true, but in the wrong order, the abstraction destroys the structure.
"And where it goes as it goes up into the body and what you are aware of in terms of its lacks and what you are aware of in terms of its ability to help you unify yourself. Realize that when you are standing with your weight flowing down on the outer arch, you are destroying the unity within yourself. Now this is what I jumped on yesterday when I came in and somebody was telling me from some book or other, it might even have been a book of my lectures, That weight has to go through the three center toes. It's true. This is the abstraction. But what is the silent level? You're feeling it right now. The silent level is talking to you. The silent level is telling you how you can get to act at one with gravity. One of the ways you can do it is by turning your toes up so as to run that line up through the middle. Certainly the negative way to do it is not to let the weight go down on the outer arch."
Ida, 1976 Boulder class, on the abstraction versus the silent level:
What the second hour actually does
The Mercury image and the two-color rule give the second hour its shape; the pulley anatomy, the dropped fibula, and the two hinges give it its mechanism; the center-line synthesis gives it its position in the body's overall organization. What remains is the practical question of where the practitioner's hands go and in what order. In the 1975 Boulder review Ida and her senior students lay out the second hour as a continuation of the first — the first hour's lengthening of the front needs a base of support, and the second hour provides it by working from the knees down to bring the foot, ankle, and leg into a horizontal hinge relationship with the ground.
"Which one is this? Both. It's both. Depends on which way you move it smoothly. There was a whole lot of need in the model that came in for balance between those two. The front was really tight and that needed to be let out and the flexors on the back also. We're very tight in those cleaning the fascia off the malleoli and bringing the tendons back into the proper place so that function would work. On the feet themselves the tendency in most of the models that I noticed was to carry the weight on the outside of the foot and in my own model he, as you'll see later this morning, he had managed to break his foot between the time his first and second hour came so he'd get huspicious. So it was a little difficult to give him a lateral arch on his right foot but that was one the things that I saw."
A 1976 advanced class, reviewing the goals of the second hour:
Ida's own intervention in this passage, when she takes the discussion back from the students, is to insist that the hinge is the focus — not the foot in isolation, not the leg in isolation, but the ankle as the fulcrum through which the body relates to the horizontal plane of the ground. The second hour is, in her late account, the hour that establishes the foundation underneath everything the first hour opened. Without that foundation, the first hour's work cannot hold.
"Different to do is balance out some of the work that you've done on the spine by lengthening the back a little bit. Well, the word balance is what we're kind of looking for. We're trying to balance out integrity of the spine there. So that's the first hour. Okay. The second hour, what you wanna do is to establish some support underneath the work that you've done on the top. When you look at the body, you notice that that the back short Allow that one of the things that you're doing at the ankle which is essentially a fulcrum for all the weight above it relating it to the horizontal plane of the ground is to so organize the ankle that it can accept the changes that you're going to create above it and that you have created. At this point, you haven't touched it and so the ankle"
Ida, Santa Monica 1975, on what the second hour establishes underneath the first:
The retinaculum and the glued pattern
If the body has been walking on the outside of its feet since toddlerhood — as Ida says most American children do — then the retinacula of the ankle and foot have taken on a job they were never meant to do. Retinacula are bands of fascia whose function is to hold tendons in place as the muscles cross the joints; they are not designed to substitute for muscular organization. But when the muscles are out of place and the bones askew, the retinacula glue everything into the pathological position. The pattern becomes anchored, and the body's chemistry follows: circulation fails, tissue hardens, the foot becomes structurally inadequate. The practical second-hour move begins, often, with the retinacula.
"Is that one of the reasons why Gail is so tripping over her feet all the time? Yeah. But it's not being I mean, the the Anchorage is higher. Mhmm. But certainly, you'll find it there. So that as they walk consistently on the outside of their feet, these retinaculate take on the job that they've got to do of holding those muscles in a good place to walk on the outside of their feet. And then the pattern is anchored. And then within the pattern, you get the change of the individual structure, of the individual chemistry of the structure, of the failure of circulation through the structure, etcetera, etcetera. And now all at once, you have a totally inadequate foot. And maybe you have a foot that no longer really sits under that ankle."
Ida, RolfB2 public tape, on how the retinacula anchor the pathological pattern:
The work on the retinacula is not, in Ida's framing, a question of dissolving or breaking anything. It is a question of restoring sliding — of allowing the muscles their strings to find positions appropriate to the joint movement the practitioner is asking for. The movement demand, and the manual freeing of the retinaculum, are coupled. Without movement, the retinaculum work is sterile; without the retinaculum work, the movement demand cannot find its expression.
"Well, near an amazing lot of joints in the body, and certainly the joints in the arms and the joints in the legs. You have muscles held into positions by retinaculate. And retinaculae is our good old fascia again under a different name. And you've gotta go in and get those retinaculate sufficiently stretched and organized and elastic that you can get some movement under them. Those retinaculae are there to hold the strings of the muscles in place. It's as simple as that. And if the string is pulled so tightly and can't be moved and can't be loosened, nothing can happen. The muscles can't move."
Ida, on the retinaculum work and the movement demand:
What weight distribution actually means
By the time Ida is teaching the 1976 advanced class, she is impatient with students who reproduce her teaching as a recipe without understanding the logic. A student in that class tries to recite the three-center-toes rule and Ida pushes back — not because the rule is wrong but because he is using it as a closed-end claim rather than as a piece of a larger picture about weight distribution. Weight, she insists, is not supported by the arches in some passive sense. It is distributed by them. And the distribution depends on which arch is doing what.
"And I guess when we look at the point of the least amount of energy invested in the movement, then it will naturally not only to a certain amount of possibilities whereby I must say that I have to go by your method, what you said about it, and have to investigate in the future if I approve of it. Okay. Now you're still talking sense. Keep on. From there we found out yesterday that maybe my assumption that the weight is going through the three torques may not be completely right because Okay, now how are you going to tell? Peter made me aware of the fact that we have two arches, not only one. I was of the opinion that the outer arch was mainly for the maintenance of balance. What is probably true in stand but not in walk. I don't know. I can't say that. But if the weight as you said or if the arches as you said are here to support the weight then I have to consider that both arches have to take on the joint. Wait a minute, it's not support the weight, it's distribute the weight. How do you distribute weight"
Ida, 1976 Boulder, in a Socratic exchange with a student about weight and arches:
Behind this insistence is a methodological commitment that Ida states clearly in the same class: the practitioner has to look at what is, not at what the recipe says. The Mercury image, the two-color rule, the inner-three-toes statement — all of these are abstractions that organize observation but do not replace it. The body in front of the practitioner has its own version of the pattern, and the work consists in reading that version and responding to it, not in applying the rule mechanically.
"It would the weight transfer then goes exactly at the junction between the two arches. According to that diagram. The inner three toes. There's much more weight really goes through to the big toe into the second toe. The first three toes. Wait. Did you say inner three toes or center three? First three. First three. First three. Three. One two three. Excuse me. I wrote down center. Alright. Okay. There you go. Crux of the situation where and how the great toe works."
Ida, on where the weight transfer actually goes:
The everted foot and the bunion
The cumulative end-state of a foot that has been walking on its outside for decades, with the retinacula glued into the pathological position and the inner arch fallen as a consequence, is the everted foot — the foot Ida says every illustration in the standard anatomy book of her time happened to depict. The eversion is not natural. It is the visible result of sharpening on the outside, lengthening on the inside, and gluing the whole pattern into place. Where the eversion has run long enough, the great toe shows the consequence: bunions, in Ida's account, are not isolated joint pathologies but the cumulative migration of every muscle in the great-toe complex by a quarter-inch or a half-inch off where it belongs.
"of every foot in this book is of an averted foot. How do you get an everted foot? Consistently everted foot. You get it by sharpening on the outside, lengthening on the inside, And all of this is then glued into place with the two retinaculum, the one above the ankle and the one on the foot itself. And there it is. This happened. Recognize the fact these boys recognize the fact that the lines of force for the foot should be like this, but they don't recognize the fact that the minute you evert a foot and turn it outward, you don't have that, and you can't have that. And the guy that wrote this book had all the evidence spread out right in front of his nose."
Ida, RolfB2 public tape, on the everted foot and the anatomy book:
The corrective work, then, is not principally a question of pushing the outer arch up from underneath. It is a question of individualizing each muscle, of restoring sliding where the retinacula have glued things, of demanding movement at the joint that has not been used as a joint, and of allowing the bones — fibula, talus, tarsals, metatarsals — to find their relationships. The outer arch comes up as a consequence of this work, not as its direct target. The wings on Mercury's heels were the visible sign of a foot that was woven, balanced, sliding, and free.
"Now, actually, what you are going to have to do in order to get those feet back is to get every one of those muscles individualized, eyes. Each one doing its own thing. Each one sliding across its neighbor when it needs to. Each one balanced in tone and this means balanced in chemistry and balanced in energy. And then you've got something to stand on. Now the actual practical bit here is to start with the retinaculae because that's where the things get the worst glued up. Not the worst. Anyway, it's practical."
Ida, on individualizing the foot's musculature:
Above the foot: the change spreads
The reason the second hour matters in the larger ten-session series is not that the foot is intrinsically more important than other parts of the body. It is that the foot is the body's contact with the ground, and the alignment established at the ankle and foot propagates upward through the legs, pelvis, and spine. Ida names this propagation explicitly in the 1975 Boulder class, in conversation with Michael Salveson: each horizontal hinge brought out below the ankle reflects itself upward, and the change in tissue tension at the ankle releases energy that spreads through the body.
"And so you really need to use the back after you free the feet to close-up and to integrate or partially integrate the person before you send them off to really open up and lengthen that back. Well yesterday someone, I don't know who said it to me, it's Michael Salison's concept of the fascial tube which starts in the cervicals and goes in the second hour when you start working on the ankles you're heading vertically again. Know that each horizontal that you bring out down below reflects itself upward as we saw in Takashi yesterday where he's working on his leg and you can see his rib cage absorbing the change. I mean this, when the tissue is in tension, that's stored energy that you release into the body. And its energy is not a metaphysical something. These molecules are aligned in a particular way. You change their alignment. The change spreads."
1975 Boulder, a student summarizing Michael Salveson's fascial-tube concept with Ida in the room:
This is why the second hour, in Ida's late teaching, is described not as a discrete session but as a continuation of the first hour and a preparation for the third. The first hour begins the lengthening from above; the second hour establishes the support from below; the third hour returns to the body's center with the support now in place. Without the outer arch lifted, the support is missing, and the work above cannot stabilize. The chain runs through the wings on Mercury's heels.
"What does matter is you understand you have to lift that up off the pelvis to start getting mobility in the pelvis. Uh-huh. The first hour is the beginning of the tenth hour. Okay? Uh-huh. The second hour is a follow-up of the first hour. Uh-huh. It's just the second half of the first hour. Okay? And the third hour is the second half of the second and first hour. It's literally a continuation. I clearly I clearly saw, you know, last summer that continuation process and how and, you know, Dick talked about how, you know, the only reason it was broken into 10, you know, sessions like that was it because the body just couldn't take all that work."
1975 Boulder, a senior practitioner articulating how the hours continue one another:
Coda: what the wings mean
Ida did not invent the Mercury image. She inherited it from a classical iconography that her older American students still recognized from the telephone book, and she pressed it into pedagogical service because it carried, in a single visible figure, the doctrine that she could not get her students to hold any other way: weight on the outside, lift on the outside, wings on the outside. The Greeks, she said, were not depicting a flying god. They were encoding a structural claim about the principle of transportation, and the placement of the wings was their way of saying which part of the foot did the work. The second hour of the recipe, in her teaching, is the recovery of that ancient observation.
What gives the image its durability in her classroom is that it is not finally about feet alone. The outer-arch lift is the entry point to a body-wide reorganization: it changes the relationship of fibula to tibia, of foot to ankle, of ankle to knee, of leg to pelvis. It restores the center line that running weight on the outer arch had destroyed. It propagates upward through the fascial tube. And it does all of this not as a direct mechanical intervention but as the consequence of restored sliding, restored hinges, and the appropriate demand for movement. The wings on the outer arch are the visible sign that the foot has remembered what the body is for: getting around, fast and satisfactorily, at one with gravity.
