I have never been more disappointed with a pair of shoes. I loved the tread, I loved their light weight, and I'm not gonna lie, I loved the colors. Unfortunately, from the second I put them on, I realized what others had mentioned - the arch was too far back and too high (note that I have worn Nike's for 15+ years, which are known for high arches, and never had a problem). They were SO uncomfortable. I even tried taking out the Montrail insoles and replacing them with a pair from a favorite pair of Nike's. It helped a little but not nearly enough and after about ten minutes of walking around in my apartment, my feet were in serious pain. Actually two hours after taking them off, I'm still in some pain. I had to return them.
