I got 10.5 which is my normal size. The width was fine, the toes were fine, but it always felt like my heel was slipping around inside the shoe, like it might even come off if I tried to run fast. So I returned it for a size 10. This felt like it was crushing my toes (like size 10 normally feels on me) but still felt loose on the heels. If it feels that way new I can't imagine the material doesn't loosen up a bit over time and get even worse.<br /><br />It's a shame because I like how they look and I definitely like not having to lace them whenever I put them on, but it looks like zipper is the only alternative that will work for me.
