With the Chung Shi DUX Trainer, it is not the shoe that guides the foot but the foot of the shoe, which promotes surface sensitivity and the feedback process between the wearer and the ground, resulting in a sensitive and dynamic balance with the entire foot. The shoe structure is strongly oriented to the natural mobility of the human foot. Stability elements such as the heel counter and the fixed shaft have been deliberately omitted to promote tactile perception. This surface sensitivity is additionally supported by the elastic DUX material used in the sole area. Depending on the body weight, the Chung Shi DUX Trainer achieves a dorsiflexion of up to 2%. The DUX Trainer is an ideal complement to conventional sports and running shoes. It promotes the natural mobility of the foot and optimally utilizes the performance of the foot muscles. Special attention should be paid to the innovative Chamude upper of the Chung Shi DUX Trainer. It is based on the latest advances in ultra fine microfiber technology and offers excellent resistance to aging and breath-ability. The properties are very close to those of natural skin.
