Ankle brace is a lightweight ankle protective orthosis, suitable for patients with frequent ankle sprains, ankle ligament injuries, and ankle instability. It can limit the left and right movement of the ankle, prevent sprains caused by inversion and inversion of the ankle, reduce the pressure on the injured part of the ankle joint, strengthen the ankle joint and promote the recovery of the injured soft tissue. Moreover, it can be used with ordinary shoes without affecting the walking gait. We can often see the elderly and athletes use ankle braces, and all kinds of ankle patients also need ankle braces to maintain their joints. Not only do we need ankle braces to keep warm in winter, but in fact, in sweaty summer, we frequently go out and into the air-conditioned environment, and we also need a suitable ankle brace to reduce the load on the joints. Made from composite material, these neoprene ankle braces are breathable and comfortable, and feature straps for easy on and off.
