I love these shoes! But … I bought them thinking I could fit my size 9 foot into a size 8 1/2 shoe. (In my defense, my last pair of the same shoe was that size. My feet are apparently growing. Aaaugh.) These have a sleek mesh upper with a chunky zig-zag midsole and lightweight fuel foam for optimal balance of cushioning and support for heel to toe comfort! I never wore these, but in full transparency, I noticed a small smudge on the rear of the left shoe when I took the photo’s (see photo), otherwise they are perfect in every way!
