M.D.
Being up in Minnesota and having my husband that works outdoors all year, he says to layer, use base layers (which work wonders!!). I don't think the UGGS are worth the money, I got a pair of sketcher boots that are "like" UGGS and they work great BUT if they get wet they are wet for days. I had to go camping the other weekend for a class and it was freezing out and I had on a regular pair of socks, a pair of wool socks and my hiking boots and my feet were warm the entire time - when we woke up the next morning it was 31 outside but it felt like 21.
