I’ll change my socks every day, and more if I’m swapping out workout clothes for fresh clothes.

Oddly, I really don’t experience foot odor. Other bits can get rather ripe, but whether I’m wearing boots or going barefoot, my feet just do t get funky. That said, I have had athlete’s foot and I’ve seen what happens when someone doesn’t change their socks after days of marching and working in the field. I know it’s not a major danger for me at this point, but I’ve got a whole drawer full of socks, and in any case I want them to match with my shoes and pants.
