When I first saw crocs I thought they looked pretty silly but then I figured out why people like them; they are shoes you can throw on and not really worry about getting your shoes dirty or wet and they are just comfy and relaxing. Now I wear my crocs everywhere and these ones actually have some leather on it so it doesn't look completely childish. I've even worn these on my motorcycle although that's probably not recommended. If they get muddy I just run water over them in a sink and dry. The nubs inside don't hurt at all and help prevent the foot from sliding. The only complaint I have is the tread on the bottom seems like it gets worn out faster than normal shoes, but otherwise they are great sandals.

Oh another thing I really love about these is the back part of the strap can be flipped up over the shoe so if you want to wear them in "slipper mode" without having to step on the back strap. Very cool.
