Thanks for the ideas, Jolt! I've seen several references to the Onitsuka Tigers and Puma H-Streets as good "barefoot" shoes. I can wear sneakers to work, and have been known to run around the office in my socks (depending on who's here!). I'll definitely be looking for those....

I'm giving serious thought to a pair of VFF KSOs....I just need to convince myself that something I'm probably too self-conscious to wear in public is still a justifiable purchase!
