I was very reluctant to order these for an upcoming beach vacation, but because of my husband's persistence, I finally did.  He gets a new pair every year and swears by them.  I can now say, I do too.  I can't believe how comfortable they are!! Perfect for poolside or the beach.  You have to order at least one size up though.  I wear a 9 1/2 in most shoes, but in these I ordered size 11 and they fit perfectly.
