As a female with wide feet, I order men's sandals as they are D width vs B width for women sizes.  My son purchased a size 12 and when I tried it on it felt fabulous ... just too long.  So, I purchased a size 8 (I wear women's size 10) and it was narrower than the size 12 but the length was good.  Not sure they will stretch out at all but am hopeful as I just need a tad more width.  Love the color & quality so will keep the sandals and try to stretch them that tad.
