I am just getting back into long-distance running after 4 decades away from it. I am older and a bit overweight, so my inner thigh has started to chafe a bit as I am now running 8 to 15 miles per run (honestly never though I would see the day when I did those distances again). These underwear are perfect to prevent chafing. They are super comfortable and they really work well, you won't go wrong. David Archy is a genius! Buy these if you chafe, regardless as to the sport you play. They are worth the money!
