Runderwear Men’s Running Boxer Shorts have been designed to provide a modern fit, giving exceptional comfort, support and control. The 5" inch inseam offers protection to the thighs and silicone leg grippers hold them in place during exercise. They have been constructed using 360° seamless technology, which means there are no side seams or tags to reduce the risk of irritation against your skin. Carefully positioned micro-perforations make the fabric breathable, optimising airflow and core temperature control.

Very comfortable

Very comfortable and worth the money.

Great to hear that you found the Runderwear Boxers to be comfortable and worth the money! We love to hear this.

Nick Shorter
Super comfortable

I'm an Ergonomist so I'm always looking for usability. Comfort is often best described as a lack of discomfort - you only notice a lack of comfort, you never notice comfort. I didn't get on with the briefs, but the Boxer Shorts where brilliant. Long, hot runs are a recipe for niggles and discomfort, but I never got any of that wearing the Boxer Short. No post-run sudden shower-screaming!

Thank you for your feedback, Great to hear that you find the Boxers to be very comfortable and they were the perfect style for you. We love to hear that your long runs were comfortable and you were chafe free!
