My daughter absolutely loves these pants she now can run 10 miles easily with no more sore irritated legs ,these pants are so soft and well made and some how fit her perfectly .these seem a little expensive but they really are worth it.just try them

David Cheung said: Does what it says and more!

With so many different products to help with running, I was a little sceptical about these underwear but I bought two pairs to see what they were like. They came in good time and well packaged and they have the logo outside and a little message in the band. They are comfy and supportive and after several long runs, I have had no issues with soreness or chafing. A few reviewers have commented on the lack of choice of colours and I would have to agree but otherwise they are a great product.

I've now tried all three styles of pants offered by Runderwear and have been happy with all of them. They are really comfortable and don't chafe.

Claire H said: Great running knickers!

These sit a tad lower than the full briefs (but still not low) which suit me a bit vetter. Very comfy to run in even in the heat. If definitely recommend them

Jason Powdrell said: Very impressed

I ordered 2 pairs of the men's briefs for my running as on my last half marathon I suffered with a bit of chafing.
Since I got them I've run 4x10 mile runs in hot weather-they've been great. Supremely comfortable, light to the point you feel like you're not wearing anything, and most importantly no chafing!
No problems with delivery, they arrived very quickly and were well packaged. Absolutely recommended 100%, worth every penny.
