i dont know of a better ,boot sock, i have 2 pair, use in knee high boot,,bird hunting ,an ice fishing pack boots, the sock has excellent fit,does not creep down,comfort is outstanding,added toe and heel insulation,ez on/off.light weight. an it seems it is holding up well in wear areas...........what more can one want.

They are super warm and very comfortable in even my tightest fitting boots. I am an avid outdoors man in the Rockies and enjoy winter camping. The heal has primaloft insulation so there is a walking on butter, or mushy feeling for the first few miles. I have gotten used to it and havent seen any loss in difficult technical placements. On vertical ice it may be an issue, i dont know yet. I have used these on cold hikes in snow territory and my feet/toes stayed comfortable at temps that used to bring a chill. I would recommend them to anyone trying to get a few more years out of their old insulated ski/hike boots or as an intermediate when you dont want to wear plastic boots.

Amazingly warm and comfortable. I wore them on several below freezing days on Kilimanjaro with mid-weight hiking boots and I was the only one in the group with warm feet. Overall, a great sock if your feet tend to get cold or you are heading to extremely cold areas.

I have used these socks Hunting,Hiking, and Skiing. Great comfort and warmth. Paired with a Silk Liner, your feet will stay warm and dry working in the cold rainy weather, and any other conditions. Helps my feet from being tired after a long day's hike.
