Anyone have some experience with warm foot gear such as socks and boots. I bought some 1000g rubber boots but I think they bullshitted on it. Feet still get cold. I hunt in Ohio and as long as it any crazy wind I'll sit in stand in the 20's if not lower. I want the best damn socks and boot available. Especially for my father who takes blood thinners. Also any thought on these battery operated inserts for boots. Every time I try and do a review on a boot, sock etc.... you get different answers. Thanks in advance
