Isn't that the truth! My wife and I love to walk along the shores of the St. Martin beaches (especially Orient) and when the waves come in it always washes away the sunscreen. So, the tops of both feet got sunburned (again). Tried beach shoes in the past, but it just doesn't generate the same feeling when walking the shore, and they always collect a ton of sand in them. Oh well, my feet are tanned now.
