Ergonomic systems which provide medical therapy, comfort and enhanced function are provided. Surfaces are provided with adjustable contour, transient force damping and temperature. The technologies are applied to footwear, seating surfaces an cryotherapy devices. The cooling and cryotherapy system employ an evaporator in close proximity to skin, and therefore employ methods to reduce risk of frostbite. Advanced control and power supply options are disclosed.

[ What is claimed is:] [12.]12. A cooling system for biological tissues, comprising:a source of volatile refrigerant having a vapor pressure at 40.degree. or greater than atmospheric pressure;a cooling matrix, proximate to the biological tissues, having a flow path for coolant, formed within walls of a polymer substrate, the polymer substrate conforming to the biological tissues and providing a heat transfer surface and being adapted to operate with an unloaded flow path pressure of less than about 5 psig;a flow passage from said source of coolant to said cooling matrix; anda valve allowing coolant to flow into said source of volatile coolant and restricting outflow therethrough.
