We used a burly 3.0mm Idro-Perwanger Roughout Leather upper for classic mountain boot performance and fit. This 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.

• Ideal terrain: General mountaineering and heavy backpacking
• Compatible with various non-automatic, semi-automatic, and automatic crampons. Crampon compatibility is NOT ensured, and boot-crampon compatibility needs to be inspected
