Bought a 10 and it was only slightly small. Not enough to get an 11. Since they are sandals its ok. I wanted to buy them last year and didn't want to spend that much on shoes thru the mail, but this year I really needed them and loved the colors. I got them and they are prettier than on Amazon. Love them. Wear them all the time to work, kids school and to dinner. Great well made shoe has nice thick stitched cushioning that I can wear all day. No breaking in and NO blisters....just comfort!
