It's hard to beat alpaca-blend socks that are designed for durability and comfort.  Our Adventure socks are alpaca blended with polyester, nylon-silver, and elastic.  They are moisture-wicking and provide odor control as well as thermal regulation. Notice the reinforced heel and toe, arch support, and inside terry-loop construction.
