Fungus Among Us?

I’m curious: What is your opinion regarding footwear in the office?

A. Employees should wear shoes at all times.
B. Slipping off your shoes at your desk is acceptable, as long as you wear them whenever you get up and walk around the office.
C. Footwear, schmootwear…comfort is priority #1, even if that means spending the whole day walking around the office in socks.
D. Shoes and socks are overrated; walking around the office barefoot is totally acceptable.

Please discuss.
