Abstract

A sock knitted from a yarn of non-feltable textile fibres, e.g. synthetic fibres. Into the sole, heel and toe regions of the sock is knitted a yarn of feltable textile fibres, preferably wool, forming loop pile meshes therein. After knitting, the sock is subjected to a fulling treatment, whereby the fibres of the yarn knitted into the sole, heel and toe regions of the sock are felted, thus forming soft fibrous layers internally as well as externally in these sock regions. The loop pile meshes and the subsequent fulling treatment thereof make the sole, heel and toe regions of the sock soft and pliable. Because the entire sock is knitted from non-feltable yarns, the sock obtains the desired elasticity and good fit. After fulling the loop pile meshes from a tight structure capable of absorbing and distributing perspiration moisture.
