If you figure out best electric socks let me know ! nothing worst than getting cold out hunting. I* blew out my 1000 gram cemented sole leather hunting boots last year and haven't got around to buying a new pair (got a lot of different boots) I don't like any cemented sole boots for serious hiking/hunting I much prefer old school quality leather, re-soleable, re-buildable boots i.e stitch down construction, at least this type of boot construction will give you a warning when the soles start to let go. Been using a combination of socks depending upon how cold and type of boot I'm wearing, really cold snow hunting usually nylon socks under a good med to heavy wool socks, and I take multiple pairs of socks and xtra boots , usually 1 pair of insulated camp pull on boots for nature breaks at night , 1 pair of medium insulated leather boots 400 gram, 1 pair of heavy leather 800 to 1000 gram boots and sometimes a pair of heavy nylon/rubber air bob Sorels. which still get cold if just sitting around and not moving. Next week will be taking my uninsulated Whites smoke Jumper boots with heavier wool socks it might snow. Coldest I've ever been elk hunting my dad's old friend gave me a pair of U.S.Army glosches /over boots to put over my leather hunting boots, and my feet never got cold and the temp was never above 20 below for a week with snow, in a wall tent, they were a life saver. get them at surplus stores or online for about 20 to 40 bucks , not easy to walk in but your feet aren't as cold either. I'm darn sure not above getting a couple pairs of electric socks the older I get.
