Episode notes
Human Feet Are Remarkably Complex
- The human foot is an extraordinary, highly complex structure with a quarter of the body's bones concentrated in it.
- Anthony Redmond highlights 26 bones per foot, multiple joints and detailed mechanics that make feet both delicate and highly functional.
Feet Switch Between Shock Absorber And Spring
- The ankle and subtalar region act as a hinge and a multi-directional joint allowing the foot to alternate between flexible shock absorber and rigid lever.
- Anthony Redmond explains rolling the foot inwards flattens the arch for shock absorption, rolling out tightens it into a spring for push-off.
Fat Pads Work Like A Mattress Under Your Foot
- Fat pads under the heel and forefoot act like a mattress with coiled columns to absorb shock and distribute pressure.
- Redmond describes connective tissue surrounding fat columns that maintain spring-like shock absorbency.
