La Sportiva Trango Tech GTX notable features

- The La Sportiva Trango Tech GTX is a low profile mountaineering boot that can be used for technical terrain and low-grade climbing routes. It can also be worn by backpackers for multi-day trips. Its synthetic fabric upper is coated with Thermo-Tech Injection for durability and lightness. A Gore-Tex membrane lines the upper to prevent water intrusions.

- The boot sports a low-density polyurethane (PU) midsole that delivers cushioning. Its La Sportiva Cube outsole is manufactured in partnership with Vibram to deliver multidirectional grip on most types of surfaces.

Size and fit

La Sportiva’s Trango Tech GTX is a high-top boot for male and female mountaineers. Its conventional lacing system, which extends toward the toes, helps wearers adjust the boot’s volume. Brand designers incorporated an ergonomic tongue made of soft stretch fabric, which gives an enveloping fit.


The Trango Tech GTX is equipped with a low-volume Cube outsole. This component is the result of a collaboration between La Sportiva and Vibram. It has a pattern of multi-shaped lugs across its profile to give traction over virtually all types of terrain. The sole’s front tip features a Climbing Zone for added control in uphill conditions. It is also equipped with an Impact Brake System to optimize braking power during a descent.


Mountaineers are supplied with cushioning and shock reduction by the La Sportiva Trango Tech GTX’s low-density PU midsole. It is covered in a protective PU skin for durability. A thermoplastic polyurethane (TPU) insert is positioned in the rear. This component allows crampons to be attached to this mountaineering boot.

The Trango Tech GTX’s 4mm polyphenylene ether (PPE) insole has increased thickness in its middle zone. This design supplies the wearer with arch support and extra comfort underfoot.


This La Sportiva boot-type product features a synthetic QB3 waterproof fabric upper with Thermo Tech Injection. The latter refers to a thermo-plastic material over-injected to the upper to reduce its overall weight and minimize seams. Moreover, the Gore-Tex Performance Comfort membrane lines the upper to provide both water protection and breathability.

The La Sportiva Trango Tech GTX (men’s and women’s) uses the brand’s patented 3D Flex System. It allows the user’s ankle to move more freely without compromising support on uneven terrain. The boot’s front end is reinforced with a rand for added protection from bumps. Its ergonomic tongue gives comfort while preventing debris from entering the footgear.

The boot’s lace closure employs a series of metal hooks, loop hooks, and fabric eyelets. These components allow the wearer to manage the fit. A pull tab is located at the back of the collar to facilitate easy on and off.

Upper. The La Sportiva Cube GTX sports a multi-layered upper consisting of QB3 waterproof fabric, Flex Tec2 fabric, and a Gore-Tex Performance Comfort laminate. The latter is engineered to provide optimal water protection while allowing excess perspiration to escape from the inside.

Midsole. The Trango Cube GTX’s midsole is made using a combination of PU and ethylene-vinyl acetate (EVA). This midsole construction allows the mountaineering boot to support the user’s weight and resist wear and tear. Its thermoplastic polyurethane (TPU) heel section has a crampon attachment. It is coupled with a 4mm graded nylon footbed for added arch support and underfoot comfort. On the other hand, the La Sportiva Trango Tech GTX’s midsole details can be seen above.
