The RUSH TRK GTX is the new benchmark for short or day hikes in the mountains. It's a boot built for comfort with technologies to help reduce foot fatigue while hiking. The right mix of comfort, stability and low weight. WEIGHT 555g Size 42 UPPER The upper is made of 1.7-1.9 mm thick Perwanger suede leather with waterproof, breathable, and durable characteristics. Thanks to a 3D Autofit collar in padded fabric, the ankle area is well protected while the foot is stabilized without pressure points. LACINGComposed of a system of cords that redistributes pressure evenly and allows you to easily adjust the closure of the upper, without compressing it. LINING GORE-TEX Extended Comfort membrane. The laminate is made of a highly abrasion-resistant and quick-drying fabric lining material, while the highly breathable membrane has a remarkable ability to disperse heat. In this way the feet are protected from water, while the sweat created inside the shoe can quickly escape. SOLEThe Presa TRK-01 sole is made of a SUPERGUM compound with high grip and durability, a pronounced heel and lugs that favour braking on descents and grip on climbs. In addition, the IKS (Interactive Kinetic System) technology, characterised by 7 shock-absorbing areas (domes), progressively and specifically supports the weight of our body during our activity in the mountains.
