Yup. Just make sure you cut a hole between your big toe and second toe. That can get really uncomfortable after a while.

That actually gives me an idea for a new invention. All those old guys down at the beach like to wear socks with their sandals, but they always have to wear non-flip-flip sandals. A sock with just a sleeve for the big toe and another for all the other toes would open up a whole new world for those guys.
