A leg brace isolates a lower extremity of a leg to which the brace is secured. The leg brace includes an upper leg cuff and a lower leg cuff. Two upper struts are attached to opposite sides of the upper leg cuff and extend along the upper leg cuff. Two lower struts are attached to opposite sides of the lower leg cuff and extend along the lower leg cuff. One hinge pivotally connects one upper strut and one lower strut and a second hinge pivotally connects the other upper strut and the other lower strut. The hinges can be configured to have a limited and/or selectable degree of rotation (e.g., flexion and/or extension). Bottom ends of the lower struts extend beyond a user's foot of the leg to which the leg brace is attached. A foot is attached to each bottom end of the lower struts.
