I first found these shoes at Shoe Carnival last year and had been looking for a second pair ever since. They are so comfy- and this coming from a woman who can't stand flip flops with that thing between your toes! If you cook or stand a lot at home, BUY THESE SHOES. There's something about the foam that keeps my feet from hurting, especially after cooking or doing laundry for an hour or more. I bought a black pair for inside and a brown one for outside. As for my old black ones? I wear them outside now. They've never slipped off- even when running for the bus! Get the 2 pack. I'm a witness...
