A therapeutic fabric boot that warms the calf and foot, permits ambulation and provides for moisture absorption and selective exposure and ventilation of the covered extremity. An internal foam cradle restricts foot movement and reduces pressure at the heel and calf when lying in a supine position. A re-sizable, flat, hinged foam extension piece extends from the cradle and folds to protect the heel, sole and toes. Several fleece lined fabric cover panels selectively fasten about the foot and calf via hook and loop fasteners. An L-shaped splint mounts in a pocket space of the boot and offset calf and heel portions of the splint further distribute the weight of a wearers leg and foot away from the wearers heel and onto a resting support surface.
