Ankle Mobility 03:37

The subtalar joint is the torque conversion system of the lower limb, taking sagittal motion and converting this into tri-planar movement. Proper rearfoot and forefoot mobility must be present in order for this conversion to occur.

The talocrural joint (a.k.a. the ankle) is made up of 3 separate but integrated joints. Success in gait, squatting, and all other ground-based movement depends on this joint complex to function properly. This movement ability is often lost through inactivity or repetitive movement with rigid footwear.
