La Sportiva men's high alpine boots Trango Tech GTX blue 21G634729 (ZFMS054634729)

Discover new heights with the innovative high-altitude boots La Sportiva Trango Tech GTX, designed for alpine hikes and technical approaches. The lightweight, flexible construction of this model guarantees unparalleled support and comfort.

The upper, made from durable material using Thermo Tech Injection technology, is abrasion resistant. Additionally, it is equipped with a GORE-TEX Performance Comfort membrane, which ensures breathability and waterproofness. Special structures made of thermoplastic material allow for seam minimization and weight reduction. Full-length lacing enables precise adjustment, and the use of hooks with loops further reduces weight.

The Trango Tech GTX model features a soft and flexible tongue integrated with the upper. Combined with an ergonomic shape and compact external dimensions, these boots are extremely comfortable and ideal for prolonged use. 

Impact Brake System
Innovative La Sportiva brand technology applied to the sole of mountain boots for walking shock reduction, traction support and improved ground grip. The unique placement of the tabs ensures maximum impact absorption.
3D Flex System
Technology patented by Italian brand La Sportiva involving a special lacing system between the upper and lower part of the shoe. It ensures a perfect fit to the calf for optimal wearing comfort.
GORE-TEX® Performance Comfort
A versatile technology used in most trekking boots. It provides the boots with resistance to very adverse weather conditions. It is characterised by being waterproof, windproof and breathable.
Vibram® Cube
A specially designed sole which, thanks to a thin mounting layer between the outsole and midsole, has been fitted with lower profiles.

    How to measure the length of your foot - instructions in 4 steps

    1. Prepare a sheet of paper and set it on a hard, non-slippery surface - it is best to tape it to the floor.

    2 Stand barefoot on a piece of paper - distribute your body weight evenly and set your foot straight.

    3. Mark the tip of the big toe and the back of the heel - preferably holding the pencil vertically.

    4. Take off the foot and measure the distance between the marks - this is the length of the foot. Repeat for the other foot and choose a larger measurement, matching it to the size chart.
