Review (5/5): Flip Flop Toe Guards
It's a great product and does exactly what it's supposed to - allow you to wear toe thongs without irritation. I use a touch of Vaseline with them between my big toe and the second toe. Unfortunately, the adhesive on the bottom doesn't stay very long but this really doesn't present much of an issue. When these wear out or I buy more toe thong shoes, I'll buy more.
