Built for the City. Ready for Adventure.
Cold wind, rain-soaked streets, or unexpected snow—Stryn Urban Hiking Boots handle it all. The 100% waterproof PU upper, inspired by traditional fisherman’s gear, keeps moisture out while staying flexible and durable. Inside, the Merino wool lining locks in warmth without overheating, ensuring dry and comfortable feet all day. The Vibram Traction Lug Concept outsole delivers reliable grip, and a reinforced mudguard adds extra durability. Whether in the city or exploring rugged paths, Stryn offers warmth, traction, and protection without compromise.
Innovations
Nature Lab is our initiative to research, test and develop shoes in a more sustainable way. This shoe uses the following innovations:
#1 – Component reduction - Waterproof PU
We designed this shoe with fewer components by using waterproof PU. Inspired by fishermen’s raincoats, this durable material keeps water out without extra layers. By removing traditional waterproof membranes, which wear down over time, we created a long-lasting, waterproof shoe with increased durability.

These shoes come with a size insert, designed to improve fit and reduce returns. Offering half sizes helps, but it also creates stock and production challenges. Instead, we developed a size insert that adjusts the fit by half a size, ensuring a better fit without extra production. If a shoe feels slightly off, this simple solution makes it just right.
