With the chung shi Trainer the shoe doesn´t rule the foot, the foot rules the shoe. As a result the wearer´s sensitivity to the surface he or she is walking on as well as the feedback process between the wearer and the quality of the ground underfoot is dramatically enhanced. The shoe is constructed with a strong emphasis on the natural movement of the human foot. We have purposely avoided stability aids such as heel supports or a firm shaft in order to promote the tactile awareness of the wearer. The wearer´s sensitivity to the surface underfoot is even further enhanced by the extra elastic DUX material that is built into the sole area. Depending on your body weight the chung shi Trainer attains a dorsal flex of up to 2%. The DUX Trainer represents the logical development of traditional athletic trainers and running shoes. It promotes the natural movement of the foot and uses the musculature of the foot to the maximum degree. Special mention should be made of the innovative chamude outer material on the chung shi Trainer: Chamude is based on the latest results of ultra fine microfiber technology. It is an amazing scientific advance because of its outstanding durability and ability to breathe. It almost has the same qualities of natural skin.
