Ankle braces provide protection by applying pressure to the ankle joint. As a lightweight orthopedic support device, they are suitable for preventing ankle sprains, ligament injuries, and instability. They help restrict lateral ankle movement, prevent sprains caused by inversion, reduce pressure on injured areas, reinforce the ankle joint, and promote soft tissue recovery in damaged areas. Generally, braces should be snug for optimal effectiveness, as they are made of elastic materials designed to tighten around the joint, effectively creating an additional protective layer. If worn too loosely, they may not perform well during exercise and only serve a warming function. However, the brace should not be overly tight, as this could impair blood circulation.
