The Nepal Trek Evo GTX is a men's mountaineering boot from the brand La Sportiva, designed for classic mountaineering and demanding trekking.
An evolution of the Nepal Trek model, it features the upper of the Nepal Evo in a lighter and less rigid construction, offering greater comfort when walking while retaining the necessary support in the mountains. Its GORE-TEX® waterproof and breathable membrane, combined with a hydrophobic leather upper, effectively protects the feet from moisture. The 3D Flex System promotes natural ankle mobility and precision of footing, even on technical sections. Its snug fit ensures precise support without compromising comfort. Underfoot, the polyurethane midsole with differentiated thickness incorporates shock-absorbing inserts at the heel and forefoot to enhance comfort on rough terrain. The Vibram® sole with Impact Brake System technology improves traction both uphill and downhill while reducing impacts on hard surfaces. Finally, its removable tongue with integrated ventilation system allows the fit to be adapted to the foot’s shape, while the EZ OUT system facilitates quick lace release for fast adjustment.
The Nepal Trek Evo GTX thus accompanies you on your mountain adventures by combining walking comfort, support, and reliability on the most demanding terrains.

| 3D Flex System | A multidirectional upper joint that allows the ankle to use its natural characteristics without losing stability. This provides greater foot control with better support, a firmer endpiece, and a wider ground contact surface. |
| Impact Brake System | An innovative system applied to the sole to absorb negative ground impact, boost traction on ascents, and improve grip on descents. The unique positioning of the lugs allows the maximum number of them to be in contact with the ground, ensuring optimal impact absorption. |
