Stream crossings in winter are my biggest issue. Should you cross with dry-fast trail runners and no socks on then put goretex socks on over your wool socks when you get to the other side and hike on? Or should you put on crocs and cross then dry your feet off and put all your shoes/socks back on-this way your footwear is dry?
I would like a way to just walk through streams that aren't too high and not have to change your clothes so often. This can be tireing when there are repetitive crossings.
I would like to see an article specifically for frequent winter stream crossings.
What about a giant plastic sock thing with tough shoe material sides/bottom that was say 2 feet tall that you could just slip on over your whole footwear system and cinch tight against your thigh with a draw cord-up near the crotch. Could be 100% waterproof material down to the foot, then turn into kind of a slip-on lightweight tough sock/shoe at the bottom. You slip it on with your boot/shoe on, never having to take them off.

Of course these would double as camp shoes.
Some kind of lightweight rubber or sock like the vincere grip boat sock:

with plastic/waterproof material that ran up the leg attached to them, that way you don't have to take your setup on and off when the stream is high. Or just a simple thin rubber shoe thingy, like a mitton, but for a foot. Whatever is lighter.
