Safe on all terrain
A clever feature is the lightweight Liba®Smart rubber protection on the toe ends; this highlights the fact that Sonnblick GTX feels right at home on steep sections of rocky ascents. On prolonged alpine tours, climbers benefit from the combination of shock-absorbent PU midsoles at the rear and rigid TPU torsion plates at the front of the foot to offer comfort and stability in equal measure. The anatomically adapted tongue construction prevents creases and folds from occurring that otherwise lead to compression and abrasion points on extended tours. Secure contact with all ground surfaces is guaranteed by the Vibram® Multifilm sole. Dachstein’s waterproof, breathable GORE-TEX membrane provides reliable protection from moisture, whatever the weather. Every single aspect of Sonnblick GTX is produced in Europe, underlining Dachstein’s insistence on the highest possible quality standards.
Caring for membrane footwear
Membrane footwear is also no stranger to water!
After cleaning and drying your footwear, boots with a protective membrane must under no circumstances have oily or greasy care products rubbed into them. Such products help to make leather goods waterproof, but in membranes they cause the build-up of water between the membrane and the outer material, preventing the release of humidity. As a rule, membrane footwear doesn’t require any care after cleaning. However, although the membrane ensures the shoe or boot remains basically waterproof, the uppers should still be impregnated regularly with a Durable Water Repellent (DWR) spray. Usually, such footwear has already been DWR-impregnated prior to sale. Nevertheless, this protection can wear off with intensive use. This protective effect can be regenerated by coating outer surfaces with one of the many DWR sprays on the market. It is far easier to impregnate shoes with a spray than it is to immerse an item in a DWR solution, as is often the case with clothing.
Hooks and eyelets can be protected from rust and corrosion by applying a dab of Vaseline or wax. There are special sprays to combat unpleasant smells. The insoles can wear out and should be replaced regularly, since they absorb the majority of the sweat produced and are subject to the greatest amount of wear.
Cleaning trekking boots outdoors
Jump in the stream!
On multiple-day tours it’s important to rinse off the worst of the dirt carefully at the end of the day in a stream or by using another source of water. Subsequently, laces should be fully loosened and insoles removed. Our tip: Even after a one-day tour, stepping into a stream makes cleaning at home much easier, because the dirt doesn’t get a chance to dry on.
