A true revolution in the world of mountaineering boots, LOWA has utilised cutting edge technology to make the Alpine SL GTX a super lightweight crampon compatible boot. By using PU as a protective layer on the outside of the boot, the weight is significantly reduced from previous generations of mountaineering boot using heavy rubber, without compromising on strength or durability.



What do you get when you bring together the world’s best moun­taineers? Something completely new! The athletes on the LOWA PRO Team worked with LOWA on the ALPINE SL GTX and scru­tinised every detail. True to the motto “less is more”, the PU scree collar is now being sprayed onto the robust synthetic material to shed weight. A carbon shank and extremely light Vibram®-Alp-Trac®-SL utilising the innovative Vibram Litebase outsole technology reduces the weight further. The end result is a colourful Alpine boot that weighs just 550 grams per boot. Whilst reducing the weight, the moun­tain­eering boot experts kept stability in mind. Other key details include a func­tional dual-zone lacing system and a waterproof GORE-TEX lining. When you add it all together, you get a light Alpine boot that performs like a pro on the mountain and is making a strong impression on Alpinists.

Independently adjustable lacing zones, one on the forefoot and one on the upper, for an improved individualised fit and better adjustments for personal comfort and different foot anatomy.

This flat support zone under the toes makes easy scrambling possible thanks to a more secure foot placement.

The overall height of the midsole is kept to a bare minimum, reducing space to the ground providing natural feel, grip and stability on all terrain.

Toe area of the shoe is designed in such a way that the distance to the rock is kept to a bare minimum, to create a good feel between your toes and the rock.

The minimalistic lacing strip produces both the highest level of functionality and maximum weight reduction. The two directly interwoven bands are easy to tie and the lacing is optimally threaded.

Highly breathable, durably waterproof lining material. Keeps feet pleasantly dry and offers optimised climate comfort for a broad range of outdoor activities.

The upper material of the LOWA REPTEX prevents damage caused by objects like sharp rocks. The reinforcement reduces weight compared to rubber, and increases perfomance on the mountain.

The use of large pieces to form the upper eliminates the need for stitches, creating a high degree of wearing comfort, and prevents possible friction or pressure points.

This product can be resoled by a specialist. They're designed in a way where the upper of the shoe is retained, and a new sole can be added to it.

The boot has a pronounced front welt, but no rear welt, so are suitable to take a semi-automatic crampon.

To reduce the stress caused every time the foot is planted, and make heel support more comfortable, a heel cushion was developed for the shank as a way of creating a pleasant walking sensation.

This footwear is 100% vegan friendly, not using any leather or animal glues in the construction.

Particularly rigid, the midsole will remain firm even when subjected to stress.
