A few months ago I had a shin splint (unknowingly at the time) which turned into a stress fracture and ended up wearing an air cast for a month. It turns out I run heel to toe and trying to change my running style is almost impossible. These shoes are the EXACT type of shoe I needed to prevent future injuries! They feel like you're running in a cloud and I've had no pain in either tibia since. Thank you Reebok!
