12 Pairs of long thermal socks in size 6-11. No fuss plain colour thermal winter warm socks. Ideal for wearing everyday or for working outdoors with boots. As they are solid colours colours they can also be worn for multi use purposes such as walking, inner ski socks if needed to add that extra warmth. The gentle welt offers comfort and protection from harsh cold weather, and looped terry for extra warmth and comfort. These thermal socks are thicker than the other thermal socks which have the word THERMAL around the velt part which we also have available.
