These are very comfy, good breathing, great looking shoes, however they do run big for the women's sizing. I (a female) wear an 8 1/2 in most athletic shoes. These are unisex and the box said that it was a men's size 7 and also a women's size 8 1/2. But in my experience, men's and women's shoe sizing runs 2 sizes apart. Therefore, I sent these back in exchange for the women's size 8 (men's size 6 1/2).
