Trail running is not just the most popular sport of the year. Running on unpaved roads is also a trend sport for every season. Even in soaking wet, muddy or snowy conditions, thanks to the robust PU coating (REPTEX® SPORT) and integrated GORE-TEX membrane, the tear-resistant jacquard material of the FORTUX GTX upper ensures that your feet stay warm and dry and can breathe freely at all times. When it comes to comfort, the LOWA® TRAC® sole system, composed of a partic­ularly pronounced DYNEVA midsole with a high rebound effect, plays an important role. Teamed up with the grippy, well-profiled, slightly curved rocker-shaped rubber outsole, it ensures efficient rolling prop­erties. Another compelling feature is the GORE-TEX Invisible Fit tech­nology offering greater flex­ibility, comfort and breath­ability, along with the promise of “GUAR­ANTEED TO KEEP YOU DRY”. A practical speed-lacing system that allows you to adjust the fit of your trail shoes rounds off this dynamic trail runner. All in all, the perfect running shoe for successful long-distance hauls.

    • Lightness
      Weight is a critical factor for athletes on the go. This is why LOWA’s trail­running shoes are really light.

    • Speed
      “Speed is key.” With this thought in mind, LOWA developed an innovative trail-running collection.

GORE-TEX Guar­anteed weather protection

Guar­anteed weather protection, even in pouring rain and heavy snow: The FORTUX GTX is equipped with a GORE-TEX membrane. The innovative tech­nology delivers optimal waterproof protection and breath­ability.

  • Permanently waterproof
    The membrane provides reliable waterproof protection. No matter what sort of adventure you may be planning, you can count on GORE-TEX tech­nology to keep your feet pleasantly dry.

  • High breath­ability
    Designed with optimal breath­ability in mind, GORE-TEX shoes provide pleasant comfort even during intense activities. Water cannot penetrate the footwear, and moisture produced inside the shoe escapes through billions of pores in the GORE-TEX membrane.

  • Windproof
    The GORE-TEX membrane dependably fights off the wind and the weather. As a result, you can head off on a tour no matter what the weather is like.

Anyone who has ever run an ultra knows how important it is to be able to brave the elements. Depending on terrain and route, it is not uncommon to encounter all four seasons along the way. In preparation for all eventualities, the new FORTUX GTX is equipped with a waterproof, breathable GORE-TEX membrane which enduringly protects running feet from getting wet.

LOWA x GORE-TEX – Nature Clean-Up

Nature provides us with all sorts of unique oppor­tunities to experience unfor­gettable adventures and enjoy very special moments. More and more people are making a conscious decision to get back in tune with nature. But the decision by more and more people to get back in tune with nature also results in a greater and greater impact on the envir­onment. You hear words like “awareness” and “mind­fulness” a lot in discussions about this trend – but what exactly do people mean when they use them? An example: The practise of taking your trash home with you after a tour now comes second nature to many people. Such steps, no matter how tiny they may seem, can be the key to a mindful and sustainable outdoor lifestyle. But if you look around outdoors, you will certainly see many places that certainly have room for improvement.

MINIMAL SEAMS Fewer stitches for lots of comfort

Stitches and material overlaps are elim­inated in the FORTUX GTX thanks to the use of large pieces in forming the upper. This reduces the possibility of pressure points, a feature that enhances comfort.

Midsole

100%
Poly­urethane (PU)

Poly­urethane (PU) is a soft plastic that has very good cush­ioning prop­erties and is usually used in the midsole as a result. Through the use of PU, the soles become light­weight and func­tionally flexible.

100%
EVA

The acronym “EVA” stands for “ethylene-vinyl acetate”. It corresponds to an elast­omeric polymer that is used to make plastic materials. The EVA material creates soft and flexible qualities. It is primarily used in the production of shoe and shoe midsoles to provide step cush­ioning. Various degrees of rigidity can be achieved on the basis of the thickness employed.

Insole

Fabric

Our natural and synthetic fabrics facilitate optimal warming and moisture management with the help of their usage-specific char­ac­ter­istics. Thanks to their structural design, they are smooth and make our products extremely comfortable.

Mesh

Mesh is a material that consists of many evenly spaced holes. It is usually made of polyester or nylon and basically a lattice-like material that is created by interwoven threads. Thanks to its special design, the man-made fibre is partic­ularly permeable to air, has special moisture-regu­lating qualities and is easy to care for, breathable and crease-resistant.
