External Supporting System
At Footjax we consider the external supporting system to include everything under, and on your feet. This includes the ground, shoe, insole, orthotic, sock, tape, brace, etc… The different combinations of these layers under your feet have a significant influence on your body’s biomechanics. In fact the external world under foot dictates how the body must function.
Friends don't let friends run on concrete
Consider a few examples:
Barefoot training may toughen you up if done at appropriate volumes
Socks can wick sweat, prevent skin irritation, compress, improve circulation, add warmth, etc
Too much traction builds up torque within the lower limb and can lead to overuse injuries
*MORE IS NOT MERRIER*
BUT too little traction can lead to slipping and falling
Shoe cushion is important but can have various thicknesses, drop, rocker, materials, weight, "control", etc...
Shoe "last" is the shape of the inside of the shoe. You will find some companies last fits you better
Tape supports weakened but functional injuries
Grass is a GREAT running and walking surface!!!
