Runderwear solved my chaffing problems and since 2018 I never run without them. Up to marathon distance with no pain or problems. Highly recommend

Absolutely love these shorts. Comfortable, breathable, no riding up your thighs and adjusting them, these shorts stay put, look great and feel great. I’ve used them for training and racing and even over a marathon distance in hot conditions I’ve stayed chaff free.

Hey peeps, Im overweight and want to loose weight. I do a lot of cardio and you know.. Chaffing and rashes blah blah. This purchase was one of the best i did. It is comfy. Your jewels take a while to get used to it. But it does the job. I can now walk continuously in the UAE humidity without any worry.

The product seems really well made, I wore one pair on 2 long runs and with a different size/ style I believe would be great.
Unfortunately my only issue is in the sizing, the length is very short and so is not long enough to prevent inner upper thighs rubbing/ catching. The longer option would be my recommendation as the boxer short is almost like a brief.

Trail run 30k and no blisters at all. Best socks I ve found as of now. Thank you guys
