La Sportiva Karakorum

This boot begs for abuse again and again. We used a new tapered 8mm high-density Nylon® that provides a smooth flex and protection throughout the boot, which allows for new-matic crampon compatibility and long-lasting consistent flex.

• Ideal terrain: General mountaineering and heavy backpacking
• The 2.8mm Idro-Perwanger leather upper is ideal for water repellency, breathability, and durability
• An SBR Aircushion sole provides cushion and helps insulate from cold or hot climates
• Aggressive Vibram® sole (semi-automatic crampon attachment)
• Multi-directional 3D Flex™ hinge promotes easy flex and a faster break-in period
