Wool meets wool in this understated high cut – to keep feet comfy and toasty warm. The black upper with its herringbone pattern is made from 100% virgin wool sourced from our partner Nordwolle, and reflects the natural fleece color of the Pomeranian sheep whose wool was used to make it. The interior lining, which likewise comes from Nordwolle, is made from felted wool loden. It turns North Wolf into an out-and-out warmth-providing, naturally moisture-regulating, water-repellent Wildling shoe. Worn less than ten times, but warn in urban snow, so there is some evidence of salt at the base of the black upper (visible in photos). Very warm. I usually wear a Men's US 8 1/2, but these fit me perfectly and are listed as a Men's 8/Women's 9. The EU size is 41 which is my usual EU size. All shoes by this company are unisex.
