Any construction with a terry pile surface on one side and a ribbed or plain knit surface on the other. In most cushioned athletic socks, the terry forms the inside of the foot portion of the sock. Some of more complex constructions feature added layers of cushioning under certain areas of the foot, depending upon the sports activity for which the socks are intended. Cushion constructions are used in men's and women's athletic and casual socks of all types. While terry cushioning normally fulfills a functional purpose of reducing shock of running or jumping, the same terry-knitting procedure is followed in producing novelty socks with a terry or velour outer surface.
