The La Sportiva KARAKORUM Boot: A versatile leather mountaineering and backpacking boot perfect for light duty mountaineering, heavy hiking and backpacking or various types of outdoor work situations where you need durable support and all-day comfort. Sizing options are shown in Men’s size. 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• Multi-directional 3D Flex™ hinge promotes easy flex and a faster break-in period• Compatible with various non-automatic and semi-automatic crampons. Crampon compatibility is NOT ensured, and boot-crampon compatibility needs to be inspected Sizing Chart: Mens: EU: Womens: 2 33 2.5 2.5 33.5 3 2.5+ 34 3.5 3 34.5 4 3.5 35 4.5 4 35.5 5 4.5 36 5.5 4.5+ 36.5 5.5+ 5 37 6 5.5 37.5 6.5 6 38 7 6.5 38.5 7.5 6.5+ 39 7.5+ 7 39.5 8 7.5 40 8.5 8 40.5 9 8.5 41 9.5 8.5+ 41.5 9.5+ 9 42 10 9.5 42.5 10.5 10 43 11 10.5 43.5 11.5 10.5+ 44 11.5+ 11 44.5 12 11.5 45 12.5+ 12 45.5 13 12.5 46 13.5 12.5+ 46.5 13.5+ 13 47 14 13.5 47.5 14 48 15 49 16 50
