An ankle brace includes a foot and ankle holder made from a flexible fabric having a foot portion transitioning to an upper ankle portion with opposite first and second sides. The upper ankle portion has an open front and back. A rear portion is attached to partially enclose the open back. The rear portion has opposite first and second panels that removably attach to the first and second sides of the upper ankle portion, respectively. An optional tongue is located at the open front and laces overlie the tongue. A rigid heel support is disposed inside the foot portion, and the heel support may include pivoting joints. Elongated support straps extend under the foot portion and wrap around the ankle holder. Retention straps extend around the ankle holder.
