The American Traveler Alpaca Sock 100% alpaca yarn boot sock.  Made in the USA! Brian says, "After many years of selling alpaca this latest design offers so many of the features our customers like: a functional, attractive, durable and comfortable every day alpaca sock. These are my FAVORITE socks! We got these in a year ago after a year of prototyping I've been wearing them pretty much non-stop ever since! Winter, summer, whatever. They are surprisingly warm when needed but breath really well when your feet are hot.  Your feet stay sweat-free-dry.  Sometimes I even wash them! :) They're so "odor-phobic" they just keep going and going." The American Traveler Alpaca Sock features a small dense soft terry loop interior for just a bit of cushioned comfort without bulk. Enjoy a tall comfortable top for a gentle yet good grip (no slouching), reinforced heal and toes and a strong double plated construction for long wear and support during long walks or being on your feet all day.
