H said: Does everything it promises!

Extremely comfortable to wear, washed well and dried quickly. I was so impressed that I bought another pair

Nick Brock said: Good to wear

Great underwear- does what it says on the tin. No chafed or sore areas - even on long runs of over 2 hours. Seamless socks are the best I’ve tried as well. Will be back for more.

Comfortable to run in with no blisters so far.

EW said: Marathon Tested

I have to admit that I have run commando for the past 10 years and was always under the impression this was the way to minimize chafing. HOW WRONG WAS I. I ran the Berlin Marathon yesterday in 22 deg heat and I have not a single hot spot. RUNDERWEAR IS THE SOLUTION!

Paul Baker said: anti blister socks

The socks do as it says on the label they minimise friction and therefore reduce greatly the risk of blisters....I am 72 years old and use these for a long day in the field metal detecting,walking many miles...well done on a good product.
