Real Alpaca. Real Warmth.

3x warmer than wool

Alpaca fiber traps more body heat to keep feet warm in freezing, wet conditions, from first light to last.

Wicks Moisture Fast

Pulls sweat away fast and won't soak it up like wool. Feet stay dry, even in wet boots.

Bought these socks for my winter trip to Colorado, I usually have issues with my feet sweating so much but not with these socks! Definitely worth the money 10 times over keeping them warm and dry.

I’ve worn these Boot socks a few times now and they are definitely the warmest socks I’ve ever had without making my feet sweat. They are also very soft and comfortable. No issues in my boots!

These are my 2nd pair that I bought just for our winter ski trips to our cabin in the Sierra Nevada mountains. I really didn't need a 2nd pair because I wear the same pair for the whole trip. They keep my feet warm in cold snowy weather and never smell.

Growing up outdoors, I learned that socks DO matter. I began job working in a freezer warehouse with temps between 0° and -20° F for 10+ hours a day, so I knew I wanted warm and durable for my job. These have not disappointed.
