The Lowa Zephyr MK2 GTX HI is a mission boot with the ideal balance of maneuverability, lightness and stability. The HI-CUT upper provides the support needed during skydiving and fast roping. The upper is made of a combination of water-repellent, tear-resistant suede and abrasion-resistant, breathable CORDURA® material. An innovative locking hook makes it possible to adjust the laces individually at the forefoot and ankle. The waterproof, highly breathable GORE-TEX Extended Comfort laminate is ideal for use in temperate or relatively wet environments. The double-layer PU midsole with a MONOWRAP® frame surrounds and supports the foot like an exoskeleton. The ZEPHYR MK2 GTX HI is certified as a work footwear according to EN ISO 20347:2012. It is antistatic and has a cold and heat-insulating sole. The outsole is not only non-slip - it is also resistant to oil, gasoline and contact heat. GUARANTEED PROTECTION AGAINST THE WEATHER - EVEN IN HOT TEMPERATURES. GORE-TEX Extended Comfort Footwear Guaranteed protection against the weather, even in hot temperatures: The ZEPHYR MK2 GTX HI is equipped with a GORE-TEX Extended Comfort footwear membrane. The innovative technology offers optimal waterproof protection and breathability. Permanently waterproof The membrane provides reliable waterproof protection. No matter what kind of activity you're planning, you can count on GORE-TEX technology to keep your feet pleasantly dry. High breathability GORE-TEX shoes are designed with optimal breathability in mind and are a joy to wear even in intense activities and hot weather. Water cannot enter the shoe, and moisture produced in the shoe escapes through billions of pores in the GORE-TEX membrane. Windproof The GORE-TEX membrane reliably repels wind and weather. This allows you to go on the road, regardless of the weather. LACING WITH TWO ZONES, SO THE SHOES FIT WELL Thanks to the two-zone lacing system used in the ZEPHYR MK2 GTX HI, the forefoot and upper have their own separately adjustable lacing zones. This allows the shoe to be individually adapted to the anatomy of the foot and strung in different ways for climbs and descents. DOUBLE INJECTION, UPPER AND SOLE BECOME A FIXED UNIT For effective cushioning and increased comfort, the sole of the ZEPHYR MK2 GTX HI is attached to the upper in a technically demanding injection process. The upper is placed in a specially designed mold. Then several layers of PU foam are poured into it. During this process, the sole and upper material are fastened together. Lightweight For this process, a plastic called polyurethane is used. It is a very light foam filling. Damping The plastic polyurethane is a foam filling with very good damping properties. The plastic retains its shape and bounces back to its original state, even when the millions of small bubbles are often pressed together. This, in turn, creates a good rebound effect. A wide range of design options Thanks to direct injection, the sole can be designed in a very large number of ways. Due to the versatile properties of the materials used, the shoes can be effective in a large number of areas. STABLE FRAME With the LOWA-MONOWRAP® frame, the midsole of the ZEPHYR MK2 GTX HI offers the very best comfort. This three-dimensional design of the midsole was developed by LOWA in 1995. The frame cradles the foot comfortably and supports it when the wearer of the shoe ventures over uneven surfaces. The sole design is slightly raised for shoes with a STABILITY FRAME. Good conductivity of the foot The foot fits optimally in the shoe thanks to the three-dimensional design of the frame. Increased comfort The special design of the midsole ensures that the foot fits well in the shoe. The foot is pleasantly cradled by the three-dimensional frame. Lightweight The LOWA-MONOWRAP® is made of a plastic called polyurethane. It is a very light material.
