The ZEPHYR MK2 GTX HI is a mission boot that achieves the ideal balance between agility, lightness and stability. The HI-CUT upper provides the support needed during parachute jumping and fast roping. The upper is made from a combination of water-repellent, tear-resistant suede and abrasion-resistant, breathable CORDURA® material. An innovative locking hook allows the lacing to be individually adjusted in the forefoot and ankle area. The waterproof, highly breathable GORE-TEX Extended Comfort footwear laminate is ideal for use in moderate or relatively wet environments. The dual-layer PU midsole with a MONOWRAP® frame surrounds and supports the foot like an exoskeleton.
