Ahhhh, these shoes. They were recommended to me by a friend who is a personal trainer. He recommends all his running clients to give them a shot. Normally I stick with Asics for running and Adidas for other sports, but I figured why not give them a try? After running about 50 miles in them, I can honestly say I'm not a fan. Unfortunately, I experienced severe knee pain after my runs with these; something I've never experienced with my other running shoes. I do, however, find them extremely comfortable to walking. I can wear them all day and not have a problem. It's like walking on clouds. They are definetely worth a try, though. I've seen many reviews from people that really enjoyed them for running; they just didn't work out for this purpose for me. Still, they are a very well constructed shoe, and I love the color (it's very bright)! I did find them a little big, so if I had to order again, I'd probably go with a 9 instead of a 9.5
