Advantage trekkers are not just for us outdoor loons.
Two of the most recent Advantage trekker socks purchases have been for non outdoors people. Kate is diabetic, her feet are always cold.. They won't be with Bison/merino blend socks. Beth works tables in a restaurant. I personally have never seen a foot padding resilience equal to what the socks do for me. And the Bison/yak socks are like floating your feet 18 inches off the floor.
I wear them to work outside,, paddle my canoe through rivers and rapids,,, and on an expedition (note the Latin root 'ped' ,,, foot) in a canoe my feet are wet every day and all day. With Bison down,, my feet stay warm.
