Upper Material : Waterproof leather, hydrophobic, breath- able (5,0 mg/cm²/h), 2.5 – 2.7 mm thick Inner lining : GORE-TEX Performance: 4-layer GORE-TEX laminate, waterproof and breathable. Highly abrasion-resistant lining with fleece midlayer. Optimized-climate comfort for all year seasons and excessive use. Increased chemical protection Plastic Insole : dimensionally stable, torsion-proof, avoids punctual preasure (e.g. of stones) Foot bed : Anatomically formed, exchangeable, washable, very good moisture absorption, dries quickly Protective Toe Cap : Anatomically formed and well-padded protective toe cap Sole : Stable rubber/PU sole with a robust terrain tread, wear resistant and non-slip traction. The low-weight PU, impact-absorbing wedge in the heel area cushions every step and affords good bending comfort. The manually-applied rubber sidewall gives this sole optimal side stability. Compliant with EN ISO 20345:2011 HAIX Climate System : Climate System with Micro-Dry lining at top of leg HAIX FP System : Flex Protection, protection of the flexzone Others : Lacing system with eyelets permitting smooth movement, clamps and hooks, integrated heel bend, no side seams, rubber toe cap Sun Reflect : Reduces the heating effect of the upper leather by direct sunlight. Sunlight is reflected by the leather, keeping the leather and the feet cooler
