Socks Purchase Feedback

Glad I purchased. They are warm, cozy & like the different designs.

Susan Walker (Wakefield, GB)

Very thick and warm socks, ideal for winter .

Stacey Greens

The only negative for me is they are quite loose, they slide down my leg and come off my feet when take boots off. They still feel a little cold but no where near as cold as a non thermal sock if that makes sense. Also the colours were slightly different from picture and ones i actually selected


Great price and good quality

terri huart (Oxspring, GB)

Victoria Blount (Bolton, GB)

Paul C. (Preston, GB)
