This shoe is very restrictive. If you need a heavy shoe for motion control, this could be the one for you. I read another review complaining about sharp arches (the arch literally has a knife edge that's only lightly cushioned by the inner padding) in shoes. I bought it anyway because of the many other positive reviews, big mistake. After a few short runs, I tested them by running 17 miles. My right foot was scraped and blistered from a poorly constructed arch. I felt so good taking these shoes
