This is the right companion for serious mountaineers when the going gets down to business! This proven mountaineering boot is ideal for tough, combination Western alpine routes with mixed terrain and for expeditions into the 6,000-meter zone. The removable inner boot of quick-drying Drylex materials and 200 gm Primaloft® insulation keeps your feet warm and dry and fits perfectly. Completely new is the gaiter construction integrating GORE-TEX® that offers in part an innovative ceramic coating. That guarantees high abrasion resistance and dirt-repellent ability. The zipper is also waterproof. Plus, the proven Vibram® rubber outsole Dolent keeps weight down and offers absolutely secure traction and edging. The sole construction uses an EVA midsole plus a carbon insert, in part for optimal cushioning, but also for utmost stability and rigidity while keeping weight low. The EXPEDITION 6000 EVO RD style is compatible with all of todays fully automatic crampon systems, including step-in and hybrid.
