If I bought some good road shoes, I'd use them in a heartbeat. I was using my prized mountain biking shoes on some old Time ATAC pedals, and was sick of needlessly wearing out the cleats/soles, so I abandoned the idea.
Someday I'll find a good, fitting, non-stinky pair of road shoes at one of the used sporting goods stores in town. Then I can spring for a cheap pair of road pedals.
