Buy the thick woolly darn tough socks.

I spent several months a few years ago buying up enough for a weeks wear (they’re expensive), and not only are they aappropriate for any weather, my feet and legs don’t hurt after a long shift standing up.

My extremely crunchy buddy hiked the whole ass at in one pair without washes but in my experience they tend to loose that cushyness after two days.

They’ve got the lifetime warranty too.
