I bought 3 pairs (1 for each of the runners in our group) and we've all been back to buy more. They are absolutely unreal

As an aspiring marathon runner, I have been undertaking longer and longer runs - six half marathons this year, with the big one next year. And that’s when I discovered the pain associated with chaffing. Not fun. That’s when someone mention Runderwear. I tried the boxers. And now chaffing is a thing of the past. Hallelujah. Problem solved.

Love them! So comfy you don’t even know you are wearing them! Was skeptical but well worth the money. Never going back

I just completed a half marathon and have been wearing anti-blister running socks, they worked like a dream, not a blister in sight and very comfortable.

So comfortable and do the job they promise, love them

I’ve searched a long time for undies to run in that don’t move. Runderwear is the answer. They are the real deal.

Absolutely love these running briefs. So comfortable & no chaffing. Highly recommend as I now have 4 pairs.

So comfortable that I have thrown out everything else in the drawer! Just get them, you wont be sorry!

I wear these for hard gym sessions or long runs and they are brilliant. They maintain comfort and zero chafe throughout

No ride up into the nether regions!

Very happy with these. They stay in place fit well and are soft and comfy. Prevent that perennial problem of thigh chafe in hot weather for those with thunder thighs!

I bought these as normal boxers were giving chafing issues. Runderwear is not sexy, but very comfortable and supportive. Best underpants for running i've ever owned.

Absolutely no chafing whatsoever after wearing them for my first 50km ultra!

Have tried bra, socks and undies. New go to for running.

Super comfortable. Excellent support.
