Traditional design meets advanced technology in the La Sportiva Men's Makalu Waterproof Hunting Boots. This classic leather mountaineering boot features the La Sportiva MPEvo outsole to ensure stability and traction in rugged environments. La Sportiva used a burly 3.0mm Idro-Perwanger Roughout leather upper for classic mountain boot performance and fit. The Makalu is a full steel shank boot that will accept an automatic crampon and kick steps in snow all day without a crampon if needed. Additionally, the protective Vibram rubber rand adds excellent toe protection and the EZ rollerball hardware makes these boots easy to lace up.
