The customizable Ultra CTS™ Ankle Brace can transform from acute ankle brace to a low profile brace for activity and then back to an acute brace. The removable PerformaFit™ upright makes rehabilitation easier. For an acute injury simply attach the upright and you can remove it for activity. The Comfortable Performathane® molds to your ankle and as the injury swelling reduces, it will continue to reform to provide optimum support.
