At a rural ranch in southeastern Colorado is the family-owned alpaca-fiber sock company Phoenix Fiber Mill that started in 2012. The soft fleece of alpacas is not only warming, but it also wicks away moisture, making it a beneficial material for shoe-bound feet. Good looking and comfortable, the socks come in an array of colors and patterns, and are named after some of Colorado’s most popular mountain peaks. Costs range from $16 to $35.
