I really wanted to like these. I had tried a pair in person and the support felt great so I ordered a pair. Initially, they felt comfortable, though a little loose. There was plenty of support on the heel and in the arch. However, after two hours of walking the straps were chafing the tops of my feet to the point where they were removing skin. I had to take them off and I don't see how there could be any breaking in which would alleviate the problem. Ultimately, I think the straps were too loose for my feet and the material on the strap was a bit too grippy in the humidity, which caused it to pull and cut at my skin.
