I should have listened to other reviewers. I take 6.5 in Clark's, 7 in Clark's Wave.Coast, 7 in Reefs. 7 was way too big in these shoes, 6 fits perfectly.  These are outstanding sandals! My all-time favorite is still the Clark's Wave.Coast, but these run a close 2nd at 1/3 the price! I last tried Skechers in the 1990s when they first came out and wasn't impressed. Skechers have changed! These are well made with very supportive footbeds, good arch support and non-skid soles. Plus, the adjustable strap across the instep keeps your foot on the footbed, no flopping around (the Wave.Coast shares this feature). They are more casual in appearance but cute, and so comfortable! I saw these on a woman at the beach and asked her about them - she raved! I would have never tried them otherwise. I've bought 5 pair - black, brown, olive, orange (kind of a faded color), and navy. I recommend them highly - buy them, you won't be disappointed!
