Advice : Use the foot sizer from SIDAS to help you find the right size
The Nepal Trek Evo GTX is a men's shoe from the brand La Sportiva designed for classic mountaineering and demanding trekking.
An evolution of the Nepal Trek model, it features the flexible upper of the Nepal Evo but with a less rigid sole unit, making it lighter as well. This shoe keeps your feet dry thanks to its waterproof and breathable GORE-TEX® membrane and its hydrophobic leather upper. In terms of comfort, the 3D Flex System frees the ankle for a natural stride with good roll-off while maintaining the necessary support for demanding use. Its fit is precise yet comfortable.
With a relatively stiff sole unit, the midsole features differentiated thickness with a shock-absorbing PU insert at the endpiece and under the arch, which is highly effective. The Vibram® sole with Impact Brake System technology provides excellent grip, especially on rock whether ascending or descending, and reduces impact particularly on hard surfaces. It is equipped with a removable tongue, featuring an integrated ventilation system allowing for personalised fit. Finally, the EZ OUT system lets you release the laces in the blink of an eye.

| VIBRAM® | Outsole capable of excellent traction on mixed surfaces thanks to vulcanised rubber technology, providing high abrasion resistance. |
| GORE-TEX® | Whether for mountain sports or exploring cafés and art galleries, GORE-TEX products are designed for a wide range of activities. With reliable breathability and the "GUARANTEED TO KEEP YOU DRY™" protection, your feet stay dry and benefit from great comfort all day, all year round. From small steps to big strides, push yourself every day. |
| 3D Flex System | Multidirectional upper joint allowing 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 area. |
| Impact Brake System | Innovative system applied to the sole to absorb negative ground impact, boost traction uphill, and improve grip downhill. The unique positioning of the lugs allows most of them to be in contact with the ground for optimal impact absorption. |
| EZ OUT | Strap that facilitates and speeds up the release of the lacing block with a single quick movement. |
