summary of the video with the time for reference:

1.Function of plantar arch that is stability and mobility 1:16

2.plantar aponeurosis/fascia attachment 2:30
medial calcaneal tubercle
plantar plates
phalenges

3.forces on strut and tie rod 3:48
compressive force on strut
distraction force on tie rod/plantar aponeurosis

4.function of plantar aponerosis/fascia (WINDLASS MECHANISM) 5:20
mtp extension causes plantar fascia to become taut which will pull the posterior strut closer which will cause supination of hind foot and the plantar fascia will again become loose which will cause increased mtp extension which will increase passive flexor force and make the foot very stable.

5.weight distribution at hind foot, mid foot, fore foot 9 :56

6.problems related to hammer toe in case of diabetes 11:35

7.Muscles 14:06
intrinsic and extrinsic muscles create dynamic sling and provide stability
