Easy to put on and take off with an outer zipper. Some signs of use. No noticeable scratches or stains. Vibrant wine metallic color. Function description: Quoted from the official website ■ Three major benefits of SHM® function 1. Supports ideal walking that protects the knee joint. When the heel lands, the fins of the screw part flex with the weight pressure, 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 knee. When landing from the heel, the impact transmitted from the heel puts a burden on the knee. The SHM® function absorbs the impact with the elasticity of the rubber. Furthermore, the screw structure disperses the weight pressure and efficiently reduces the burden. 3. Stabilizes the knee. Works on the muscles on the inside of the thigh. The muscles on the inside of the thigh (vastus medialis) are responsible for stabilizing and protecting the knee during walking. The SHM® function, which promotes screw home movement, efficiently activates the muscles on the inside of the thigh and leads to correct walking.
