  • Patent number: 5425701
    Abstract: An orthopedic brace to facilitate healing of injuries to the foot, ankle or portions of the leg above the ankle includes a boot having a lower edge section releasably connected to a sole. The width of the boot, as well as the distance between a pair of upright struts located along opposite sides of the boot, may be varied to complementally match the width of the patient's foot. The struts and a section of fastening straps are located between layers of foam pads of the boot to reduce the likelihood that the straps or struts will become ensnarled with other items. The sole has a mirror image configuration on either side of its longitudinal axis, and left and right insoles are provided so that a single boot may be used with either the left or right foot of the patient.
