I used to have small amounts of lower back and knee pain from running so much, but as soon as I started wearing these...it's unexplainable, their obviously great for running but also for lifting and anything else you want to use them for. Their a little expensive, but trust me, it's worth it. Go try them on at a sports authority. Feels like your wearing a cloud on your foot.
