Wrong size items were received, disappointing as they were a Christmas present, and there is no way to be able to speak to anyone other than by email! Sent two emails and no response yet…

Good socks

Well made socks. Unfortunately, I have large feet and swollen ankles and they don't fit me. I gave them to my Nephew and he loves them

Shrunk

Tried for two days and was amazed how comfortabe and really very warm.

Washed using 30 degree cycle and unfortunately they shrunk and now so tight round my ankles. I can't wear them because i suffer from odema. Our washing machine is a top of the range by Neff and this the first item to shrink.
