  • One customer notes that the boot is a bit on the narrow side.

Bottom line

Highly admired for its robust construction, the La Sportiva Karakorum HC GTX is one of the best in its class. It gets high marks not only for being sturdy but also supportive, waterproof, and grippy. All these qualities make the boot perfect for challenging activities in the mountains.

It can be a little too stiff in the beginning but it gets comfortable right after the break-in period. But since it’s quite on the narrow side, be sure to test if it fits you perfectly before making a purchase.

  • This mountaineering boot from La Sportiva has the looks and functionality of the former model - the La Sportiva Karakorum with the addition of the Gore-tex lining. This special fabric offers superior protection from water and external moisture. 
  • The current model also features a different midsole made of expanded PU+EVA. It also comes with a TPU insert that provides reliable cushioning and support to the foot. 
  • For the outsole, the Karakorum HC GTX makes use of the Vibram Impact Brake System that performs well on uphill and downhill paths.

The Karakorum HC GTX by La Sportiva is a single mountaineering boot made with thick leather upper that takes on the shape of the foot after some breaking in. The lace clips near the cuff allow the fit of the ankle to be adjusted separately from the foot. This provides not only a secure fit but also stability, support, and ankle protection.

The Impact Brake System (IBS) of Vibram has lugs arranged in such a way that they increase the boot’s “break” or stopping ability by 20%. This is an important quality necessary for a mountaineering boot because traversing uphill or downhill paths can be totally difficult and dangerous. 

The IBS sole absorbs negative impact from the ground and increases traction, regardless of the type of terrain.

For this model, La Sportiva combined EVA and Polyurethane (PU) - two of the most common cushioning materials used in hiking shoes and boots. PU is known for being highly resilient, which means it doesn’t tend to compress or flatten over time. EVA, on the other hand, is lightweight, soft, and has low-density which has the ability to absorb impact. Together, they make a long-wearing, cushiony, and supportive midsole.

Like its predecessor, the Karakorum HC GTX has an upper made of 2.8 mm Idro-Perwanger leather which has really good waterproof characteristics even in extreme conditions. But it has a much nicer color - the mocha forest 2019. 

Like the Nepal models, this boot also features multi-directional 3D flex hinges for maximum ankle support. Inside the boot is a Gore-tex lining meant to keep the foot dry. 

Lastly, the boot comes with a robust lacing system that lets you adjust the fit around the ankle separately from the foot. It’s compatible with heel crampons, ready to take on challenging paths even in freezing temps.
