Manufacturer: Asahi Medical Walk Color: Gray Product number: KV50043 Material: Cowhide, synthetic sole Size: 23.0cm Three major benefits of SHM(R) function 1. Supports ideal walking that protects the knee joint The fins of the screw part flex with the weight pressure when the heel lands, and when stepping in, the toes rotate slightly outward. It assists the rotational movement of the knee and promotes correct walking. 2. Structure that easily disperses and absorbs impact on the knees When landing from the heel, the impact transmitted from the heel puts a burden on the knees. The SHM(R) function absorbs the impact with the elasticity of the rubber. Furthermore, the screw structure disperses the weight pressure and efficiently reduces the burden. 3. Works on the inner thigh muscles to stabilize the knees The inner thigh muscles (vastus medialis) are responsible for stabilizing and protecting the knees during walking. The SHM(R) function, which promotes screw home movement, efficiently activates the inner thigh muscles and leads to correct walking.
