FEATURED CUSTOMER REVIEW

Changed my life

"After a particularly bad week involving chafing in unspeakable areas, I googled solutions whilst limping back home. This was the first result and never has money been so well spent! They arrived quickly, fitted as described, and immediately the chafing was a thing of the past. I’m really impressed with how comfortable they are and I’ve been wearing them to keep cool during the heatwave as well (I’ve not even been running!)" - Iain B

seamless

Sometimes less is more – and for runderwear, less seams = more comfort. No side seams, no labels and most importantly, no rubbing. There’s less wastage, too – so choose seamless to run smooth and free.

breathable

The little things often make the biggest difference… Micro-perforations allow our underwear to breathe all year-round and improve airflow – which means you won’t overheat. Be cool, stay comfortable.

Great stuff

These have got to be the most comfortable running boxers. They are soft and stretchy, and I love the grips.

Warning About Leg Grip

I have worn these shorts for about four years and in general they work as advertised. They breathe and feel great, and I have had no issues with chafing. That said, I must provide a warning about the silicone leg grips. The third or fourth time I wore these, I did a six mile trail run, and upon returning home, I found that the leg grips had rubbed against my thighs and quads, causing severe blistering in lines where the silicone was in contact with my legs. While only slightly uncomfortable, the blisters did take about a month to heal, and caused permanent scarring and discoloration to parts of my quads. In light of that, I obviously cannot give runderwear shorts a glowing reccommendation, but since then I have been wearing the shorts inside out (so the grips do not touch my skin) and have had no further problems. I guess this is not a common issue, but I hope this review might save a few legs in the future!

Can always rely on these to be comfortable and not cause any chaffing or irritation while running!

If in doubt just buy 1 pair. Once you have tried them out once you will buy more 😅

Awesome boxers!

Bought these at the London Marathon Expo after hearing rave reviews from friends (and struggling with chaffing when running long distances). Used them for the 1st time at the London Marathon having not ran in them before and they were perfect! Thanks so much to the runderwear team! :-)
