I got a bit of stick when I started wearing Zems to work, but they got bored with it pretty quick. I also wore my VFFs to a race (motorsport, not running!) once and no-one really said anything. Think they might be a little much for my office though!
I could probably wear VFF's if I wanted to, but don't really care to have to buy that many toe socks. I did wear my Stems all week last week, though ironically sockless. They feel way better sockless than VFF's do IMHO.
I wear my KSO's or I am barefoot at the office all the time, but they knew what they were getting when they went after me to fill their open position. The interesting thing is now I have at least 10 to 15 of the office walking around in either socks or barefeet. People are starting to realize it is just more comfortable to be without shoes. :beer: (my son really wanted the beer on here).
