La Sportiva Nepal Evo GTX Mountaineering Boot Review

It is considered to be one of the best mountaineering boots, for sure, it is one of the most iconic mountaineering boots there are out in the market. The La Sportiva Nepal Evo GTX, is indeed, a great piece of gear for multiple winter mountaineering activities. From an easy Alpine route, to mixed climb up to ice climbingLa Sportiva’s Nepal Evo GTX is one of the most popular mountaineering boots of all time; a combination of rugged, supportive 3.2mm Perwanger leather, classic lacing system, lugged Vibram sole with rigid midsole, all lined with insulated Gore-Tex to keep a mountaineer warm and dry.

The La Sportiva Nepal Evo GTX has taken hardcore mountaineering boots to another level. This boot is at home on big mountains and technical routes. This is truly one of the best leather mountaineering boots on the market for a wide variety of alpine objectives.

The usage of the insulating Gore-Tex/Duratherm lining makes it completely waterproof and breathable. The upper features the “3D Flex System” hinge, innovative system of multidirectional ankle hinge, combined with an elastic anatomical snow protection in the back, with a small integrated elastic gaiter.

New removable tongue with incorporated ventilation system, gives the option of adjusting the fit, personalized for any foot. The EZ Out pull loop (Patent Pending) facilitates the unlocking of the lace lock. The new model weights only 2050 grams per pair. A traditional lacing system allows the wearer to tighten or loosen where needed, and is further enhanced by the presence of a set of locking eyelets just before the ankle. These D-rings cam down to lock the lower part of the Nepal’s laces in place, which gives the wearer the choice of keeping the lower and upper parts of the laces at different levels of tightness.

The La Sportiva Nepal Evo GTX cuff is padded and ergonomic, and includes a thin elastic gaiter at the rear to keep snow or other items from entering. This is actually one of my favourite features of the boot. The insulating Ibi-Thermo footbed gives the boot exceptional insulation from the cold.

New tapered HP3 midsole and shock absorbing PU inserts in the area under the heel and the ball of the foot. New exclusive sole with the innovative technology IBS (Impact Brake System), developed in collaboration with Vibram, designed to soften impact on hard ground. Another great feature of this mountaineering boot is the fact that it can be easily resoled (with the official Vibram Sole) by your local craftman. In fact, having used these boots extensively, I have already resoled the Nepal’s once.

The IBS (Impact Brake System) innovative system is applied to the sole to absorb negative ground impact, help traction and improve grip downhill.
Created and developed by the R&D department at La Sportiva, it offers real advantages during racing by reducing negative ground impact. The unique position of the lugs allows as many of them as possible to come into contact with the ground, for maximum impact absorption.

Having used extensively the La Sportiva Spantik mountaineering double boots, I can easily say the La Sportiva Nepal Evo’s are quite close in terms of warmth. The boot uses “Gore-Tex Insulated Comfort Technology“. While La Sportiva/Goretex doesn’t go into much detail about this technology there is noticeably more insulation in the boot compared to other similar mountaineering boots.

The only disadvantage compared to the La Sportiva Spantik’s, perhaps, is during multiday mountaineering trips that is not so easy to dry the boots. Other than that, the Nepal’s are almost as warm for altitudes bellow 6.000 meters.


The La Sportiva Nepal Evo GTX is perhaps the most comfortable mountaineering boots I have ever used. Of course, this is not just my personal opinion, but is a shared opinion amongst the mountaineering community. In terms of performance, I have found these boots to be precise while ice climbing but also when rock scrambling. In addition, due to the fact here in Greece the mountains are not always covered with snow from the starting point, I have used these boots also for the approach hike without any issues.

With the La Sportiva Nepal Evo GTX I have been to several mountain peaks, including
