Croc knock offs don't use the same patented material. So they won't feel the same. Crocs are ugly. They are. But they are, simply put, the most comfortable, lightweight, easy to take on and off shoes I've ever worn.

However, these same guys will happily walk around in something that looks like this: http://x9d.xanga.com/cdab40516323534675987/z23981230.jpg Somehow, old, ugly tennis shoes are socially acceptable, and Crocs are not. Honestly, men, unless you look like this: http://cache.viewimages.com/xc/51057856.jpg?v=1&c=ViewImages&k=2&d=03FC8F4A2C60278158EC03F02F49812E284831B75F48EF45 you are dressed like a modern slob, and history will be less kind to you than you think, Crocs or no Crocs.
