Embrace a more sustainable lifestyle and face winter head-on with the extra wide fit KIIRUNA GORE-TEX® boots. Designed to keep you moving through rain, sleet, and snow, the KIIRUNA winter boots seamlessly blend heritage and innovation. They feature a waterproof and insulated GORE-TEX® thermal lining to keep your feet warm and dry, deep-lugged TR-rubber soles, and a PU mudguard. Wrapped in upcycled matte grey and green pull-up Heinen leather, which develops a vintage patina due to its flat and scratch-sensitive finish, each pair gains unique character with wear over time. Crafted at our own dedicated factory in Pärnu, Estonia, we have adopted a more sustainable approach to the design and manufacture of KIIRUNA Zero Waste. These eco-conscious winter boots are created from a blend of factory scraps and surplus waste materials. LAST WIDTH: J (Extra-extra wide) UPPER MATERIAL: Upcycled dark grey and green matte leather, very quick to develop a unique patina.

Exposure to rain and snow also enhances this unique patina, as liquids darken the leather. HEINEN LEATHER: Tanned by Lederfabrik Josef Heinen, this eco-friendly choice in shoemaking prioritises environmental and animal welfare.
