How to handle a guy at work?

A guy i work with seems to be into shoes. He has remarked on several occasions that i wear the cutest shoes, up to now i didn't think anything of it. Today I was wearing some new sandals and he commented on them and my pedicure what was different is that I noticed he was um "aroused". I felt a little uncomfortable and left the room. I don't want to think he is some perv, how do i address this with him? Or do i? I don't want to embarrass him either, I know sometimes guys can't control when that happens. Advice please, he does seem like a nice guy overall.
