I wear size 37.5 and I bought size 38, and the length is OK (although it should have been slightly longer). The wide strap in front of me is big, my foot floats inside when I walk. They are relatively heavy. The metallic parts on the side of the ankle straps caused me blisters. They are very beautiful, they have a nice soft sole. I put band-aids on the metallic parts from the inside and I will continue to wear them.
