The Boreal Stetind Boots feature a fully integrated outer gaiter keeps the elements out and is neatly and simply closed with a single premium quality water resistant zipper. Inside you’ll find an upper made from lightweight synthetic textiles and a closure combining the best of conventional laces with a Velcro ‘power-strap’ at the ankle to keep your heel locked down. Triple Thinsulate™ layers surround the whole foot (even underneath!) providing superb warmth with no cold spots and a unique Dry-Line® lining ensures absolute waterproofness and superior breathability. Stetind is fully compatible with automatic crampons and uses dual density crampon lugs, hard at the rear for a secure fit and soft at the front for reducing vibration when frontpointing on bullet hard ice. The advanced carbon composite midsole is rigid, yet incredibly lightweight and ample underfoot cushioning is provided by dual density shock absorbing PU and EVA layers. Finally, a deeply lugged Vibram® Teton outsole will help keep you upright on the approach.
