Key features

Expedition construction

A classic boot with countless expeditions in extreme cold.

75 mm

Vibram® 75mm standard 3 pin bindings. Can be used with a wire binding.

Shell construction

The boot is made in water repellent Cordura with leather reinforcements. No inner lining or padding makes it exceptionally quick drying.


A comfortable and very warm ski boot that is perfect for the adventurer who will not let extreme cold put a stop to their expedition. The boot features a water repellent Cordura upper with exterior leather reinforcements for added protection and support. The midsole has been manufactured with special rubber that allows it to withstand extreme conditions without cracking. This model is built around a total concept for footwear at low temperatures. The concept consists of a thin polypropylene/nylon sock over the foot, then a vapor barrier or vapor tight sock and finally a wool inner boot or synthetic liner. These products are purchased separately. We recommend buying the boot 2 sizes larger than normal.

Certain snow/crust conditions are an extreme strain on the shoes materials, and with use under such conditions increased wear is expected.
