Built with extensive input from The North Face® Athlete Team, the Ice Storm GTX Boa® represents the pinnacle of several winter-weather technologies:
1. Steel Laces: The Boa® lacing system consists of several strands of aircraft grade stainless steel wire woven together into small bundles which are then coated with engineering polymer to provide a smooth surface.
2. Reel: When the grippy Boa® knob is rotated, the lace winds onto the spool, providing precise and easily-adjustable closure.
3. 400 gram PrimaLoft® Eco insulation.
4. Gore-Tex® waterproof, breathable membrane.
5. Bomber, abrasion-resistant-yet-breathable mesh upper.
6. Heal Cradle™ absorbs impact and stabilizes heel plant.
7. TNF Winter Grip™ on outsole periphery works in tandem with centrally embedded Ice Pick™ technology which hardens as the temperature drops.
8. Boot shape easily accommodates snowshoe attachments.
