Helen Taylor said: Anti blister socks

I bought the socks for a 12 mile charity walk, and was amazed how great my feet felt during and after the walk, not a blister in sight. I would recommend buying them for peace of mind and happy feet.

Kirstyn Brogan said: excellent support and comfort

I purchased this running bra along with a pair of runderwear pants, it might be a coincidence but I ran the furthest I ever have since I got them! The bra is a good fit and sits comfortably on my skin and does not dig in or leave marks. There was minimal bounce. The material seemed to wick away any sweat, there really was no chafing. This is certainly one of the best sports bras I have owned and the pants are a revelation!

Sally Hills said: The ultimate test!

I have been training in my socks for a 100km walk in September. So far so good, absolutely no problems and I have worn them in running shoes and walking boots. They wash up well and I am hoping the two pairs I have bought will last me the walk. Have got back up walking socks but will be in my runderwear socks for most if not all of the event Hope me and my socks make it!
