The Alta Via GV is a mountaineering boot designed for technical alpine pursuits. It features a supple and durable leather upper, GORE-TEX Insulated Comfort for waterproofing and warmth, and a Pebax frame with a PU insert for stability and shock absorption. Toe and heel welts ensure compatibility with step-in crampons, while the nylon and fiberglass lasting board provides torsional stiffness. Self-cleaning lugs help maintain traction on varied terrain.
