These exceeded our expectations! I wanted something that would be comfortable for my 8 year old son to wear on the beach and also not retain a lot of sand and make my wife crazy! Not only are these great for walking in the sand and surf; they protected his feet from shells and stones and we probably waled 5 miles collecting shells on a brisk lat March day at Ocean City! We rinsed them off before heading back to the hotel room and I could barely find sand inside of them! These are awesome and even better than advertised!
