Review on DonJoy Performance WEBTECH Support Strap by Jason Mitts

Two weeks before the half marathon I was unable to run more than 50 meters due to pain from patellar tendinitis. This harness allowed me to finish the race with minimal pain. It's way better than cloth straps (which I've tried several types of). It's totally worth the extra cost as I find lower spec products comparatively inefficient. For a sizing note, my leg circumference just below the kneecap where this rides is 13.25 inches and I'm close to the upper size limit for small/medium. I would say if you are over 14 inches in circumference go large/large.
