I bought these in black and this grey ~ (black version I have don't have back sling though) ~ these are really cute and make me feel bouncy and happy wearing them ~ the back sling is a good added feature for staying on a bit more securely.  Without the sling is much easier for those of us on the go (moms with children and dogs) I love these shoes.  I bought size 9 and often wear nine and size was perfect.  They are not meant to flop around so fit snug, but no pressure on toes and heel meets end of shoe perfectly.  I am usually barefoot and like my toes to feel free and these clogs were fine with my feet ~ at least for the part of the day I was wearing shoes at all ~
