This boot, weighs in at a super light 2lb 10oz, one of the reasons it's won favor with mountaineering gurus worldwide. The Gore Tex membrane is guaranteed waterproof, while remaining breathable. La Sportiva took their climbing shoe background to heart when they created the snug fitting Trango's lacing system with lace lock. Another feature that sets the Trango apart from the competition is the 3D Flex ankle hinge system. This support system remains flexible from side to side while providing stability when front pointing in crampons. AVAILABLE FOR NORTH AMERICAN SHIPMENT ONLY.
