The Modular Ankle Brace System discloses ankle braces that utilize modular construction and dual-hinge connections to provide support for the ankle while allowing for regular dorsiflexion and plantarflexion movements. The modular construction of the braces allow the braces to be used at various stages of recovery from an ankle injury or as a preventive brace to protect the ankle from rotation and twisting during physical activity. The components of the braces are connected with hinges that allow for support of the ankle without bulky wraps or braces over the ankle and underneath the heel. Thus, providing a more comfortable and functional ankle brace.
