The ankle guides the most basic movements and exercises of the body. It is the most critical body part that can cushion the weight of the body with the impact of the ground. According to the characteristics of the ankle joint structure in different activities, the ankle joint support is designed, which can improve the overall stability of the ankle joint and cushion the strain caused by excessive stretching of the ligament. In addition to preventing injury, these braces can improve athletic performance, limit movement after an ankle injury, and reduce load on the injured area during recovery.
