I took a big chance on these and was pleasantly surprised. Note: I am not a runner and bought them for everyday wear. (Also, I am plus sized and wear a size 11). I have a very difficult time finding a shoe that has the arch support in the right place for my foot. Can't wear Nike at all. My hips felt instant relief. The toe box IS very roomy and at first I thought I should have sized down, but since I hate to wear socks I find my toes have room to breathe and don't get sweaty. I also like the very low profile and mesh material of the upper. I wore these for working on my feet for two days in a row (on a concrete floor) and then an 8 hour power-shopping day and I have no pain in my hips, knees, or back. Pair number two should ship tomorrow!
