For unstoppable winter performance, we offer the Snowburban UltraDry™ boot. Built for winter's worst, the Snowburban comes fully loaded with 400 grams of 3M™ Thinsulate™ Ultra Insulation and a reliable UltraDry™ waterproofing system. Rounding it out is a rugged toe rand and the same articulated hardware as our top-of-the-line backpacking boot. Burly? You bet. But we watched weight at every turn. The result is a warm, durable, go-anywhere boot that's also light enough to get you back.
The ColdHold compound sole is a dual density rubber optimized for superior traction in cold environments. Harder, sharper lugs line the perimeter of the sole offering positive bite into snow and frozen turf while the center lugs remain pliable in cold temperature, conforming to irregularities of terrain. The UltraDry™ waterproofing system combines a moisture management lining with waterproof components for dry, long-lasting comfort and performance.
Fit Profile: The Snowburban UltraDry™ is built on the Perpetuum last. This last is formed on a straighter line for people with flatter feet, with a broad toe box, tailored instep, and a lower heel volume than the Arc Tempo's medium volume. The last is stable and comfortable for going the distance, and the broad toe box is ideal for endurance activities because it allows the forefoot to expand naturally. A tailored instep locks the foot securely in place to minimize foot movement, reducing friction. The Perpetuum last works great on your feet all day, whether running, hiking, or standing.
