I wore these for my weekly beach walk and it was nice not to have to worry about sneaker waves anymore. I agree with others who say they are about half a size too big. I normally wear a 10 (with moderately wide feet) and ordered the 10. They're a bit loose, especially in the heel area, but I think a 9 would have been too small. People with narrow feet might want to order the smaller size. I plan to put a pair of insoles in them and then I think they'll be perfect. (They don't have much arch support; typical for a rain boot.) I'm very happy with my purchase and love the raindrop design!
