Within two years, Lee and others fully expect mainstream shoe companies to produce and market shoes of all types and styles with soles of unequal height. Lee Cole is walking and skating proof that these are excellent mottos to follow. According to Cole 1. Almost all people have legs and arms of equal length. Most people's right hip is tilted higher than their left hip.
Pelvic tilt makes the right leg functionally shorter than the left leg.
A left-handed person's upper body always rotates clockwise over the functionally shorter right leg, exaggerating functional leg length discrepancy. Pelvic tilt increases with age and injury. If this were done, posture, strength, and balance for sports and daily activities would improve. For the article I wrote about Lee and his theory for Walking Magazine, click here .
