Here’s a handy dry sock trick I learned several years ago in Illinois that works well for snowy conditions, when you really don’t want wet socks: Put your socks on, then cover that with a long, skinny plastic bag — something like a bread bag or newspaper bag works well (for anybody who still takes a paper). Put your shoes on over the bag. Viola! Dry socks!
This doesn’t work well in temperatures much above freezing — your feet sweat — but for cooler climes it’s a very inexpensive but effective trick. Waterproof SealSkinz sockswork better, but baggies over your socks work pretty well in a pinch. I also see Goretex shoe covers but I’ve never tried them personally.
My California bike commute isn’t that long and even in the rain my socks usually don’t get wet, but I keep a couple of extra pair of socks in my desk for days like today when they did get a little damp.
I also used to keep an electric shoe dryer in my office until that day when it caught on fire. The facilities and risk management people like to avoid fire when possible, so no more shoe dryers in my workplace. The model I used is no longer available (gee, I wonder why), but I used one something like this.
