Never used but did put the hardwear on it once.
The Lowa Men's Ice Comp IP GTX Boot is a competition-worthy ice climbing boot with Black Diamond's Raptor Crampon bolted into the sole. This unique design enhances precision and performance while eliminating grievances like snow bailing. This lightweight ice climbing boot also features a durable waterproof, breathable Gore-Tex membrane with fleece lining and Primaloft insulation at the toe for warmth where you need it. Underfoot, the Ice Comp features a rigid shank for the support you need to stay on ice or mixed routes.
