Built to withstand cold temperatures and extremely harsh terrain, while also delivering unsurpassed comfort.

An exclusive Zamberlan Vibram® Darwin outsole leverages a dual-density PU midsole (one lower-density for cushion and one higher-density for support) and Vibram rubber outsole
The Vibram outsole features an excellent tread for superior grip, solid downhill braking, stable toe-off tread zones, and lugs wide enough to be easily cleaned with a stick or finger
A forward rocker is built into the boot to help propel you forward as you climb up the mountain
Italian Hydrobloc® Nubuck leathers comprise the uppers in a distinctive Shark Camo color pattern while boasting 2.8mm of tough durability throughout
The patented ZFS (Zamberlan Flex System) allows the uppers to break forward in comfort without compromising lateral stability around the ankle
The RRS (Rubber Rand System) over the toe box offers added protection against rocks and debris. The RRS has been improved from prior versions to allow for greater durability over time thanks to better elasticity and an underneath bevelled edge, which prevents catching and peeling
Corrosion resistant hardware allows for easy lacing and durability over time
Gore-Tex® Insulated Comfort membranes provide the utmost waterproof protection and breathability while granting temperature performance to approximately -20 degrees Celsius (temperature performance is highly dependant on factors outside of boot, such as sock material and user tolerance)
Lasted with the ZWL (Zamberlan Wide Last) to accommodate for insulation and extra sock layers in extreme conditions, but able to accommodate feet from D to EE in width
