I have a pair of heated socks. I believe they are Snow Deer brand and have had them 3 seasons. They come up over the calf and battery plugs in on the side of sock. If it's below 50 my feet get cold and these socks keep me hunting. They don't have a remote and you turn them off or adjust heat on the sock. Other than having to pull your britches leg up it's no problem.. To me these are a game changer if you get cold feet. And I believe you can buy on amazon
