I don't have "foot sauce" because my feet aren't cramped up in shoes all day long! I'll never understand why people think feet are so gross. Who cares? They're like hands on the ends of your legs...do you think it's gross when someone doesn't wear gloves too?
People compare me to that Dual Survival guy a lot, and they call me a hippie, and all sorts of other things. But I don't care, it feels good not to wear shoes, so I just don't do it. If that makes me a hippie, then I guess pass the joint and sign me up for Woodstock, because they're staying bare!!
P.S. I work with computers - I'm self-employed and do a lot of "hired gun" stuff. My clients think it's cool that I don't wear shoes and so far not one of them has said anything negative about it. I have had jobs where I was in warehouses and things like that where I had the foresight to put on some work boots - I might be that crazy barefoot hippie guy but I'm not stupid. Also, my hair is a pretty average length and I shave. So whatever.
