LOL.. excellent point, BUT .. in my defense I only wear them at home/garage/basement. Can wear them in my garage (where the floor is often dusty), hose them off and in few minutes they're as good as new. Can't do that with any other footwear.
P.S. flip flops can be hosed off, but I'd sooner wear Crocs in public than flip flops where no one can see me :BLAA:
