Sporting an extra high cut and an interior lining made of felted wool loden from Nordwolle, Astron is ideally equipped for cold days. The pin buckle clasp adds to the distinctive look of this Wildling shoe while ensuring a secure fit. The brushed upper in dark blue made from 100% virgin wool from certified organic husbandry lends the Astron its salt-and-pepper finish in a cinnamon hue. In tandem with its integrated membrane, it’s designed to block cold and moisture and keep your feet protected even on those long walks on chilly days. The microfiber padding on the heel provides additional protection. We recommend kneading it gently prior to first-time wear to make sure it’s supple and pliable. Please note: Every single shoe is a handmade one of a kind, with an upper made from natural material. The structure and coloration may exhibit minor irregularities. With this table, you can determine whether this extra high cut is a good fit for you.
