The Big Sky II Mid is a 7-inch insulated winter hiking boot. It has a waterproof full-grain leather upper and 200g of PrimaLoft Bio insulation. Stretch panels and pull loops make it easy to put on.
The Vibram Megagrip Granite Peak outsole is built to be supportive and protective, and it grips cold, slick terrain. The Granite Peak ACT Impact midsole uses Intelligent PU for lightweight cushioning, durability, support and rebound.
The O FIT Insole Thermal is molded to the shape and construction of each pair. Its insulated top sheet adds warmth, and a Mylar bottom sheet reflects heat back to the foot. The B-DRY waterproof system lets sweat escape while keeping moisture out.
