Rotation control prosthetic sock for use with roll-on suction suspension liners. The DERO sock minimizes or eliminates unwanted rotation and vertical movement between the outer socket and silicone suspension liner, gel interface, silicone insert, etc. by incorporating friction enhancing polymer strips into the prosthetic sock. The DERO sock provides an opportunity for silicone suction suspension in transfemoral cases where it may otherwise be contraindicated by allowing easier donning and volume management capability. The polymer strips add virtually no thickness and are vertically oriented in standard A/K and B/K patterns to allow various ply combinations, while maintaining the circumferential stretch inherent in the Soft-Sock prosthetic sock. Sold each. Patent #5,728,167 and #5,931,872
