RE: 1000 gram thinsulate question.
I don't like rubber boots. I do however, wear a pair of uninsilated for early bow and turkey season. for the cold times I wear a pair of Rockey snowstalker extremes. the problem with rubber boots in cold weather is they don't breath. if you do a lot of walking, your feet will sweat, get your socks wet no matter what kind or how many layers of socks you have on, in turn letting your feet get cold.
