The best there is


I have tried others, but this is the most comfortable and supportive running boxer I have ever run in. There is extra support where needed and they are cut shorter and curved so they don't ride up.

narrow elastic around leg holes


I am 5'7" 150lbs and I do not have huge quads. I have worn these boxer briefs on various runs and hikes (4+ miles). They are comfortable and supportive. The seamless design is a plus. The elastic around the leg holes needs to be wider. I found that they tend to ride and bunch in my crotch because of the narrow elastic band. I believe if the legs were longer or if they would use a banned similar to the waist band this would eliminate the problem. All in all pretty comfortable except the digging them out of my crotch from time to time.

way out there

Should be excellent ...


I am in marathon training and non-chaffing, supportive underwear is critical. These shorts provide these features. Unfortunately, after only 10 uses/washes the material has failed and there is a hole in them. No problem except that neither Road Runner nor ASICS will stand behind this product.
