"In the standing weight-bearing position on even ground, the internal rotation of the tibiotalar unit induces instant remodel- ing of the foot plate. The talus is internally rotated (adducted), flexed, and supinated. The talar body is in its lower position relative to the calcaneus and the talar lateral process, forming a solid male V wedge, is in close contact with the corresponding female V contour of the calcaneus laterally at the junction of the sinus tarsi and the posterior calcaneal surface. The talar head compresses medially into the acetabulum pedis, which offers an increased capacity of volume. The calcaneus is in exorotation (pronation, valgus, and eversion). The navicular and the cuboid are also in pronation, whereas the forefoot is in supination twist to maintain the plantigrade posture. The inferior calcaneonavicular ligament and the superomedial calcaneonavicular ligament are under tension. The subtalar cervical ligament and the calcaneotalar interosseous ligament of the canalis tarsi are also under tension. In this position, the talus is in a synarthrodial position at the talocalcaneonavicular joint and is in the close-pack position. With the combination of exorotation or valgus of the hindfoot and supination of the forefoot, the lamina pedis is untwisted. As demonstrated by Lewis, in this position the short plantar calcaneocuboid ligament is also under tension because of its oblique disposition (calcaneal origin, proximolateral, and cuboidal insertion, distomedial). The foot now has a lower medial longitudinal arch and is longer and wider. The lowering of the medial longitudinal arch further tenses the plantar ligaments and the plantar aponeurosis. The foot is now less flexible, more rigid, and converted to a more efficient lever arm."
The amount of observation and work you put into the human anatomy is remarkable, as a medical student the anatomy classes we had were nothing comparable to that, I wish when I graduate to take that knowledge judiciously and help other people , thank you so much ❤
I’m not sure it’s possible to walk by pressing on your heels, unless you are walking on your heels - which is an interesting exercise, but not typically what we’d call “walking.” Perhaps I misunderstand what you mean, though. I’ll be releasing a detailed explanation of walking in March. You can check out this recent video and have some input on that upcoming video if you’d like. ruclips.net/video/maFcjNgm8-4/видео.html
This video is the one that goes the most into the anatomical specifics, a few of which are probably unneeded. However, part of the point of the video is to show that you can make sense of the point of this dense scientific language. Did you watch the follow up video (the next one in this series) that goes over the same topic in a bit more straightforward manner? You can also try asking questions if something is unclear.

Can you make a detailed video about our skull and how we can influence the positions of the temporal bones?
great information,
The crewing in the foot is really true and works for me i have seen boxers do this to when rope jumping
I suffer from plantar fasciitis. Will my plantar fasciitis go away, if I make my foot more like this ideal model you described?
Tanks, I mean in to initiate a step in walking you first touch the land with your foot toes or with heel?
For me it wasnt really the tibial but more the metatarsels and the back part of the fifth
when we walk do we press on heals or toes whihc one is correct walk?

This description is far too complicated. You need to provide us with a much simplistic explanation.
