With full compatibility with automatic crampons, it is ideal for glacier traverses and ice climbing. K4 GTX is highly durable, equipped with the most innovative thermal and component technologies in the KAYLAND range. UPPERA new impactful graphic accompanies the high technicality of this shoe. The completely redesigned design with a new pattern echoes the style of other models in the range for unmistakable stylistic continuity with the new logo and pictogram evident on both sides.The fascia surrounding the boot and the toe box are made externally with Diamond Technology, an exclusive polyurethane material that offers an unprecedented degree of abrasion resistance, and with a wider surface area for greater protection. The inner surface of the toe band has also been implemented by adding rubber to provide greater protection for the foot and the SCARPA from the wear and tear of crampon use. Protective gaiter with waterproof Easy Zip closure. LININGInternally, a Gore-Tex® Duratherm lining, one of the most thermally insulating linings in the Gore range, has been included. The lining is perfect for protecting the feet even in the coldest temperatures, maintaining waterproofing and breathability of the foot while elevating the footwear's internal comfort level. FOOTBEDThe arch of the footbed is accentuated to ensure greater braking to the shoe when descending and for better grip on rocks. The Vibram® Teton sole has a specific design for mountaineering and ice climbing: full zones on the toe and heel provide more grip and increase safety, while the grippy compound maintains high grip in all conditions and on all surfaces. INTERSOLE AND UNDERBEDThe polyurethane outsole block also wears the institutional colors with a bi-color design. The rear heel for crampon insertion has been embedded and secured in the midsole to provide a more secure and stable grip. The mounting footbed is made of fiberglass with aluminum foil to ensure maximum rigidity, especially during use with crampons. The midsole features exclusive technology, thanks to the SMART PU component, the polyurethane compound that can react to changes in temperature: it hardens the heel area in colder temperatures and softens in milder weather to facilitate cushioning when walking. LACINGSThe K4 GTX offer a new lacing system from the maximum adjustment according to the intended use. The tongue features an overlap closure, with a single gusset to ensure total foot wrapping. Added to this are 3 levels of closure: a lace puller, which offers the possibility of tightening the laces and keeping the fit anatomically constant, an intermediate level with the lace closure, and finally at the top, the Velcro and microfiber strap.
