I just looked at the Crocs website and they look like regular sandals to me. What is better about Crocs than any other type of sandal? I would have thought that leather would be better than an artificial material. And what's up with the bumps inside the shoe... isn't it uncomfortable to walk on? This is the first time I've heard about Crocs and am just wanting more info about them! I would like to wear more sandals and spend less time in socks and shoes, but my feet are VERY sensitive.
