Excellent product. Bit upset that I am xxl

Peter Teague said: Brilliant socks

These are the best antiblister socks available. Have tried other brands but they don't compare. Never had another blister since I started using the very comfortable Runderwear socks. Obviously, like any socks they will wear out but you do get excellent wear out of each pair. Have done 4 marathons and loads of half marathons and they the only socks for me.

Happytoes said: Well-received gift

My husband says these are very comfortable. Having read a previous review, I bought the extra large size whereas he would normally wear large. The decision was the right one.
