I am returning these because the Chaco Women's Zvolv X2 Sport Sandal fit me better, but I liked these a lot too. They were very comfortable. I am usually a 7 1/2 and I bought a 7. I wish they had half sizes because these fit, but just barely and the 8s are a bit big. The arch is much more pronounced in this style than the Zvolv style. For me it did not feel as good, but if you have high arches this may be a good fit for you.
