Andy John said: Best socks ever!

Really pleased with the running sock, did a few 8 milers in them followed by 1/2 marathon.
Really comfortable to wear, and no blisters.
Looking forward to using them in the next 6 weeks, when I have another 3 1/2 marathons.

Nicola Hardie said: Fantastic buy

I bought these for my husband for running and cycling. He says they're fab with adequate support where it's needed.

Charl said: Wonder Woman should wear runderwear!

Runderwear is my go-to underwear choice for running, has been for a while, particularly for longer distances.
My recently ordered attire is actually even more comfortable than my previous, and the new design should make the vpl much less obvious, especially in the larger style of pant.

Dave said: check the sizing

Material is lovely and soft, and not a seam in sight, but despite ordering as per the size guide, I think I should have gone for the next size up as they were a bit snug around the leg holes! I did try them on over another pair of pants as suggested, but figured they were a bit snug due to to wearing two pairs!

I'll probably order some more in a larger size at some point.

Fozette said: Anti-VPL Low Rise Hipster

Very happy with my Runderwear purchases, having read the previous reviews I ordered these in a size Medium, I'm normally a size 10 and these fitted perfectly - so glad I took note of the reviews.

I also ordered shorts and socks in the same order and having recently had a birthday I suggested 'Runderwear' vouchers as present ideas but it turns out they're not available - such a shame.
