Product size chart is incorrect on this one. I wear a 9.5 US size. This seller says that is a 40 Euro. Not. this shoe is too short. Should have been a 41, but not worth sending back, so this pair goes to Goodwill. I feel like I wasted my $12. They don't even offer a size 41 in women's, but you can get it on the men's version. It would have been a comfy shoe, but my toes hit the front rim and curl up.
