The foot has evolved to be an incredibly advanced system. When in its natural state (without shoes) the foot moves in the most efficient and healthy way. It rolls, stretches, expands, and grasps the ground. The foot is so self-sufficient that it only works properly without shoes. Therefore, nothing worn on the foot can improve the foot's functions but only hinder them. For example the foot has its own built in system for absorbing shock: see the picture of the Foot's Natural Suspension System to the right.
- NO arch support: foot's arch needs to flatten on impact to dissipate shock.
- NO heel cushioning: heel needs to be flat & level in order to stretch achilles tendon.
- NO stability or motion control: foot uses pronation, rolling inward, to deflect shock.
- NO cramped toe box: toes splay apart upon contact softening the landing.
