Composition:60% polyamide 18% polyester 10% acrylic 9% polypropylene 3% elastane 32% bisentio® 28% nylon 18% polyester 10% acrylic 9% mythlan® 3% elastane Technology: HeliX Coil System Suppronation prohibited Air Condition in Channel® Lambertz Nichol son Achillessehnen Protektor3 ExpandLadies Stripes Narrow arrow construction Stretched ribs Intelligent compression zone Anatomically shaped footbed: The ball of the foot is cushioned and supported by an anatomically shaped footbed. The air conditioning chain begins at the arch of the foot and exits the shoe. The pumping effect constantly regulates heat and moisture, allowing fresh air to circulate with every step Foot protector with AirVent zone: The 2-millimeter high 3D knit technology prevents the material from remaining perfectly adherent to the skin and allows thus effective ventilation. Warm, moist air can escape from the shoe. The foot stays dry and resists blisters Aktiv Bund: The very elastic Aktiv Bund offers a secure fit and support without restricting movement. Traverse AirFlow Channel System: The three-channel transverse airflow system helps channel heat and moisture into the air conditioning channel. Heel protector: The heel area is particularly prone to blisters: the heel protector absorbs friction and thus effectively reduces the risk of blister formation. Toe guard: The asymmetrical toe guard absorbs pressure and perfectly conforms to the contour of the asymmetrical toe area. In this way, it protects them from blisters, irritations and injuries. ToeTip Protector: ToeTip Protector cushions and protects particularly sensitive toe tips. Shin guard: acts as a shock absorber and reduces the incidence of pressure points and the risk of injuries, scratches and bruises. Calf guard: This calf guard offers protection and ventilation: the horizontal and vertical padding contains wide channels to keep the area dry. ISO Blocker: The ISO Blocker prevents cold drafts and reduces the incidence of pressure points.
