Product Features
This product is designed to apply appropriate compression on the calf muscles to keep relaxed position that results in increasing the reflective force to improve one's performance and instantaneous force. The compression is adjustable by oneself.

bonbone Calf achieves the improvement of reflective movement by supporting the calf muscles in the stretching (vertical) direction. Although other calf supporters normally apply compression in horizontal direction for restriction of muscle activities,  bonbone Calf lifts up the calf muscles (applies compression from bottom to upper side) to maximize its potential activities to improve its performance with unique material.

Moreover, the upper layer of bonbone Calf contracts the calf muscles to keep its relaxed condition by applying compression from bottom to up sides (see the right image). 
Lifting up the calf muscles supports plantarflexion of the foot. This change influences on each step motion so that this supporter can support for the fundamental activities for walking, running, jumping and other sports.
