La Sportiva Nepal Cube GTX size and fit

The Nepal Cube GTX caters to men and women. La Sportiva has equipped this boot with an adjustable tongue which users can alter to get the best fit. Tweaking the tongue’s position and height can greatly affect the volume. It is based on EU sizes and is offered in standard width. It generally runs true to size.

Outsole

This mountaineering boot employs a resolable Vibram rubber powered by the Impact Brake System from La Sportiva. The lugs on this outsole are individually inclined which reduces impact by intensifying shock absorption. Similarly, its design renders traction and promises a more efficient braking ability. In the end, areas of articulation experiences reduced fatigue.

Midsole 

The Nepal Cube GTX has a midsole made of 2mm crampon-ready polyurethane. La Sportiva designers paired it with the 4mm-thick Carbon Tech Honeycomb insulated EVA insole. This combination maintains a light, warm and supportive ride. Carbon fibers are known for their beneficial properties including high tensile strength and low thermal expansion. They are also lightweight. With a thinner construction, a mountaineer’s stride becomes more stable with the increased ground contact, with or without crampons.

Upper

Manufactured by Perwanger for La Sportiva, the 3.2 mm silicone impregnated leather boasts of a durable and water-resistant semblance. Likewise, the natural framework of this material makes the boot breathable and resistant to scrapes. This assembly is fortified by the wrap-around air-injected rubber rands that give additional protection against bumps and cuts. Furthermore, it is lined with the waterproof Gore-Tex Insulated Comfort membrane which enhances breathability and prevents heat loss in cold weather conditions.

La Sportiva incorporated their innovative 3D Flex system on the Nepal Cube GTX. It uses a multidirectional hinge on the upper to allow the ankles to move freely without losing stability. This mechanism ensures that the foot has more control on arduous terrain while securing the heel.

This high-cut mountaineering boot has a removable tongue which aids in enhancing ventilation. In addition, its mesh fabric helps expel humidity. The elastic ankle cuff acts as a mini-gaiter that keeps off the snow.

Additional Info

  • The La Sportiva Nepal Cube GTX is resolable. The old, damaged sole can be replaced with a new one.
  • The La Sportiva recommends cleaning this mountaineering footgear after every use. Take out the removable footbed to get rid of gravel that got into the boots as it can damage the lining. Also, do not stuff papers inside the boot as they can slow down the drying process. Never dry the pair under extreme heat.
  • The brand is highly against the use of oil-based treatments on the leather. According to them, it can adversely damage the waterproofing feature and life of the product.
