I think I've heard they will let you return, so long as they aren't worn (but double check...).

By experience with the KSO is that it doesn't really keep sand out. But that's just my experience.
The black KSOs do seem a bit snugger! I recently got a pair and they are definitely a little tighter than the others--I was putting it down to them not being broken in yet but maybe there really is a slight difference. Hoping they'll stretch just a bit if I wear them with the Injinjis for a while.
