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.

The invention claimed is: 1. An article of footwear, comprising: a control system; an adjustable element effecting continuously controllable damping of footwear forces; a driver coupled to the adjustable element for adjusting the adjustable element in response to the control system; and a tensile elongated element, whose tension varies with foot applied pressure. 2. The article according to claim 1, wherein the system modifies a performance characteristic of the article of footwear. 3. The article according to claim 1, wherein the control system is electronic, further comprising an electrical power source. 4. The article according to claim 1, further comprising a sensor providing an input to said control system. 5. The article according to claim 4, wherein the sensor is selected from the group consisting of one or more of a pressure sensor, a force transducer, and a position sensor. 6. The article according to claim 4, wherein the sensor is selected from the group consisting of one or more of a hall effect transducer, a strain gauge, a piezoelectric element, a capacitance sensor. 7. The article according to claim 1, wherein said control system receives an input from a wireless user interface. 8. The article according to claim 7, wherein said wireless user interface communicates with the control system through a radio frequency communications. 9. The article according to claim 2, wherein said adjustable element stores energy, and is adjustable with respect to at least an energy loss. 10. The article according to claim 1, wherein the adjustable element is a fluidic device. 11. The article according to claim 1, wherein the adjustable element is a pneumatic device. 12. The article according to claim 1, wherein the tensile elongated element is in a sole of said article of footwear. 13. The article according to claim 1, wherein said control is responsive to at least a sensor input representing a footwear performance parameter and a user interface input receiving a volitional input. 14. The article according to claim 1, wherein the adjustable element further effects distinct control over an operating point of said footwear, separate from control over said continuously controllable damping of footwear forces. 15. The article according to claim 1, wherein the adjustable element comprises a pressurized space and an orifice, wherein said continuously controllable damping of footwear forces is effected by selectively controlling a bleed rate. 16. The article according to claim 15, wherein a pressure within said pressurized space is controlled independently of said bleed rate. 17. The article according to claim 1, wherein said adjustable element comprises a structure responsive to a force applied by a foot to the article of footwear, and wherein said adjustable element selectively dissipates a portion of the energy represented by a wearer's gait pattern. 18. A method for tuning an article of footwear, comprising the steps of: providing a tensile elongated element within the article of footwear, whose tension varies with foot-applied pressure; determining a desired state of the article of footwear; and continuously controlling damping of footwear forces by altering an adjustable element to achieve the desired state. 19. The method according to claim 18, further comprising the step of coordinating a states of the article of footwear and a second article of footwear. 20. The method according to claim 18, further comprising the step of providing a power source and actively controlling the damping. 21. The method according to claim 18, further comprising the steps of sensing a state of the article of footwear and controlling the damping in dependence on at least the determined desired state and the sensed state. 22. The method according to claim 18, further comprising the step of controlling an operating point of the footwear, distinct from the continuously controlled damping. 23. The method according to claim 18, wherein the tensile elongated element is located in a sole of the footwear. 24. An article of footwear, comprising: a tensile element, whose tension varies with foot-applied pressure on a sole of said article of footwear; an actively driven adjustable element effecting continuously controllable damping of footwear forces by adjusting an operating point of the tensile element; and a control system, comprising a microprocessor and an electrical power source, responsive to at least a sensor input representing a footwear performance parameter and a user interface input receiving a volitional input, to adjust the adjustable element to modify an operating point of the tensile element, to control at least a dynamic gait energy recovery characteristic of the footwear.
