4.0 out of 5 stars
Great item!, 21 Oct. 2013
I bought this item as when I was running 10K races, I found I was getting quite bad pain in my knee which turned out to be patella tendonitis. Since buying the strap, I found the pain was alleviated. The only reason I gave it 4, not 5, stars was because after an hour it does start to hurt so for my next goal of a half-marathon it probably won't suit but for hour-long races, it's perfect!
