Abstract: A system and a method of asymmetric shock absorption and torsion cushioning for footwear. The asymmetric shock absorption system providing an upper plate attached to the upper section of the footwear and a lower plate attached to the lower section of the footwear. The upper plate may be in direct contact with or spaced apart from the lower plate. A flexible perimeter band extends around the entire perimeter of the sole of the footwear and permanently connects the upper section to the lower section of the footwear. The flexible perimeter band may have a low-profile and extend around only the perimeter of the upper and lower plates. The flexible perimeter band may wrap around one or more plate to provide for limited horizontal movement, e.g., lateral, longitudinal, or both lateral and longitudinal, between the upper section of the footwear and the lower section of the footwear.
