I bought these because I'm new to CrossFit. I read several reviews and they were the most recommended along with the Nike version. I've always had bad luck with anything from Nike so I bought these. After a few weeks of CrossFit I find the shoe quite good. I'm also a runner and I have a good idea of what a good and a bad pair of shoes can do to you. I haven't had any problems with my feet, knees or hips so I get enough support. All of my muscle pain comes from using muscles I've never used before, not shoes.
