Socks, not even the thick wader/hunter socks, which go up even over my knees, was doing it. I noticed some stick-on handwarmers, made for the feet. Now... not all feet are created equally. Having size 15 means it takes two patches on the bottoms, and one on the tops, to warm the stupid things.
The large wool socks help, once the patches begin warming. Wouldn't mind a few higher up, say on the calf, and shin. And, maybe, sometimes. But worried about it getting too warm, and running out. Even so, these are helping with healing. Probably helping with circulation, which then helps with healing? Maybe both, straight up.
