This flip-flop fits me well. I am usually a size 10 1/2, but the 10 works. I bought it as a deck shoe alternative for sailing, for the non-skid bottom. It is a little heavier than most flip-flops, but I am very fussy about my feet and the shoes that fit.  Also I noticed that the wonderful smooth footbed (where my foot contacts the sandal) is so smooth that it is a little slippery. I suppose that will change as I wear it longer and my body oils settle in.
