Compression of venous tissue enables improved blood flow in the feet. For example, nitinol wire wrapped around a curved footbed is electrically heated and thus shrinks forcing the wire on the top of the footbed into the bottom of the foot. The wire, or group of wires, is successively withdrawn and re-pressed against the bottom of the foot from toe to heel. Athletic recovery and treatment of various medical conditions may be achieved, for example restless leg syndrome, edema, plantar fasciitis, deep vein thrombosis, pulmonary embolism, venous insufficiency, wound care, and the like.
