I'm looking at footwear for the upcoming winter and beyond. Currently I wear boots because those protect my feet on the job best. If I'm hearing snickers and giggles that's okay.

I was looking at crocs.com at noticed a pair of all terrain cold and wet crocs with leather uppers. Has anyone got any experience using crocs while pedaling their bike?
What do you wear or recommend for footwear? Only rule is not breaking the bank. I commute 18 miles a day and am on my feet all day.
