Constantly begging for abuse, the La Sportiva Karakorum Boot is always prepared to take a beating. These leather bad boys are expertly crafted to be ideal for whatever backpacking or mountaineering adventures are on your horizon. Whether you are scrambling up a wicked incline on your way to base camp, or on a weeklong trek with a bag strapped to your back, you are guaranteed a comfortable and supportive experience. Water repellant and crazy durable, there isn’t anything the Karakorum can’t handle. A tapered 8mm dense Nylon delivers a smooth flexing experience throughout the boot so that your foot gets a nice, consistent step no matter how many you have to take. The Idro-Perwanger leather upper locks out water, but is still highly breathable and durable. Aiding in insulation and cushion, the SBR Aircushion delivers comfort in all climates. Perfect for carrying you from sun up till sun down for days at a time over all kinds of adverse terrain, the La Sportiva Karakorum Boot is ready to show you what performance is all about.
