I bought a pair of these (size 9) two summers ago and when I rec'd this newest pair they were almost 1/4" shorter than the old ones of the same size. I had to return them and go one size up. Aside from that, they are comfortable but the soles are rather slick...it's just hard to find some good old fashioned flip flops that are nice and thick with a little bit of support and that's why I like these!
