Used to get cold toes, but not anymore. Get some HotMocs if you can find them, keeps the heat pads on top of your toes, outside the boot, and has a breathable material that lets the packs stay hot. You can get the LARGE heat packs at walmart when they have them. 2 of the large heat packs on each foot keeps my toes warm down into the 20's, even though I am wearing un-insulated rubber boots. Before HotMocs, I used to suffer too.
