Tips to keep feet warm?
(beehaw.org)
The simple trick to keeping one's upper body warm is adding layers. However, wearing multiple socks does not work for the feet. At least not for me. Any advice? Preferably non-electric solutions.

Try compression socks as the innermost-layer, which are long enough to run up the calf. With these on, I use one more layer of regular cotton sock and generally feel pretty warm (compared to just thick wool socks, or multiple other layers).
