A family member of mine just had these patented. Buy a pair for that special someone and wrap them with a gift certificate for a mani/pedi at their favorite nail salon. Great for Valentine's Day coming up or Mother's Day, anniversaries, etc. Women love to be pampered.
I'm no expert, but apparently normally women go in for a pedicure, they put toe separaters on them, get their pedicure, and then have to wait a long time to dry. If you click the link, you can see that the toe separaters are built into the flip flop.
This is a new spin on an old idea. Nail salons have made similar products as long as pedicures have been around, but there has never been anything like this. It's durable, comfortable, AND fashionalbe enough to be worn to and from the salon.
