A combination of a machine knit first layer and a weave fabric second layer for reducing friction between the layers is provided. The machine knit first layer comprises an upper surface with a first vector and a lower surface with a second vector or it comprises an asperities vector and the weave fabric second layer has an upper surface having a long vector or an asperities vector and a short vector, and a lower surface. The upper or lower surface of the first layer is for contact with the upper surface of the second layer, and the orientation of the first or second vectors or the asperities vector relative to the long vector or asperities vector control the friction between the first and second layer, such that in use, the layers are oriented such that friction is reduced between the layers or friction is selectively reduced for only one of lateral or longitudinal movement. |
