Runderwear™ Men’s Running Long Boxer Shorts are designed to provide a modern fit, giving exceptional comfort, support and control. The 7.5" inch inseam offers full protection all the way down the thighs and silicone leg grippers hold them in place during exercise.

Customer Reviews

Based on 472 reviews

Very impressed, nice and tight arounf the leg, no rubbing whatsoever on a 23 mile run. Pleased with puchase.

Stu D

These things are magic, i'm a 40 mile a week marathon runner that doesn't look like a marathon runner, i didn't think finishing a long run and not having some inner thigh and elsewhere rubbage was possible. However, after 26 miles in there my skin remains silky soft, buy them, will solve problems you didn't even know you had

John Archer-Thomson

Quick, efficient service and a good quality product as advertised. Very pleased.

Chris Copus

Though initially sceptical, as I could see on close inspection that the seam stitches that have caused me chaffing before are still used, I am pleased to report that the panel shaping keeps these well away from the prone areas and after 26miles, I was chaff free!! Good work guys👍

Maciej Lasota
Goodbye chafing

As a runner and pwerlifter my quads have grown giganto-normous..... sadly along with this newfound strenght comes some epic chafing. I tried other boxers, I tried chafing cream. These work 100% of the time, they magically stay down and don't ride up, meaning I can run pain free - epic find!

Thank you for your feedback, Great to hear that you are now chafe free in your Long Boxers and they stay in place. We love to hear this, We hope you have many happy miles in your Runderwear Boxers!
