I dry my shoes either open in the sun or with a cold-air shoe dryer, so they don't get so funky. Never washed them though. If you're reasonably clean once you put the socks and shoes on you don't actually *create* any new bacteria from sweating in your shoes, you just give the bacteria already there a warm and damp environment to thrive in
Drying them out fast will take care of that.
Likewise with my rock climbing shoes - the only times they get really smelly is if I walk around barefoot before using them and bring gunk into them, or if I don't get them dried fast enough after use.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
