Hi Stefanie! I found that layering for my feet worked best also. I would start with sock liners then add one or two more socks, the last one being Smart Wool, depending on the temperature. This worked pretty well for me as long as I kept my core cozy with warm drinks. If I got that chilled-to-the-bone feeling, I’d find some stairs and climb them ’til I got the blood pumping. Hope this helps!
