Traction designed for mountain terrain

La Sportiva's Trango Cube GTX provides wearers the traction they need over mountainous terrain, thanks to its Vibram One outsole. This rubber sole sports low-profile lugs which are designed to help mountaineers secure their footing on uneven surfaces.

Impact Brake System

The lugs around the heel zone make up the outsole’s Impact Brake System. This proprietary technology by La Sportiva has the lugs slanted and positioned at opposing angles to improve the boot’s shock absorption and impact force reduction by about 20% each.

Stabilizing midsole

The Trango Cube GTX’s midsole is a stabilizing rubber platform which is made using a combination of polyurethane (PU) and ethylene-vinyl acetate (EVA). Majority of the midsole is made of polyurethane which gives it the ability to support the user's weight and withstand wear and tear. Part of the heel zone and the entirety of the arch section, on the other hand, are tough against cracks and give the boot ample rebound as they are made of EVA. Its heel end, which is reinforced with thermoplastic urethane (TPU), serves as a crampon connection.

When it comes to underfoot comfort, on top of the cushy midsole, the boot also has a 4mm graded Nylon footbed. This removable insole has contoured midfoot borders for extra arch support and a perforated forefoot zone for added breathability.

Protective and insulated upper materials

With its multi-layered upper—seamless, waterproof QB3 fabric, Flex-Tec2 fabric, TPU overlay and Vibram rubber rand—the La Sportiva Trango Cube GTX gives wearers a protected mountaineering experience. Debris protection is primarily handled by the boot’s gusseted, outer tongue. Walling off water and other wet elements is the Gore-Tex Performance Comfort liner. This waterproofing technology also improves the boot’s breathability and durability. The interior, which includes the removable tongue, has enough padding for extra comfort.

Lace-up closure for a customized fit

The Trango Cube GTX’s standard lace-up system features TPU lace hooks and loops which work hand in hand with the upper’s synthetic overlay in giving wearers a snug fit. It has a pair of lace loops that the designers slightly offset from the main path of the eyelets to give wearers the ability to set their desired fit from the ankle up.

The boot’s toe box is reinforced with a rubber coating. This rubber coverage, together with the Vibram rubber rand, guards the footwear against abrasions and gives wearers extra protection against forefoot injuries and toe bumps.
