I'm a longtime Vionic fan, and these shoes did not disappoint. That arch support that we all love is there, the shoes are light and comfortable, and they work for my slightly-wide-but-not-wide-enough-for-a-WIDE-shoe, high arch, feet. Vionic sizing is tricky. In sandals I wear an 8.5 and 9 is too big. But in flats and sneakers, 9 works well for me, and that continues to be the case. These 9s are a *smidge* lose, but I can tell an 8.5 would have been too small. I'm so happy to have found these!
