This outstanding hiking boot uses a new and unique dual injection technology which pads out the boot making it thicker and more durable for ultimate cushioned torsional support.The inner/softer PU grants the boot outstanding shock absorption and is strongly housed inside the outer layer.What makes the shoe abrasion-resistant for rocky and rugged trails is the tough waterproof nubuck upper and the height of the boot that seals debris out around the ankles. The Vibram grippy outsole is a high-performance rubber compound that adopts a strong shape and stance and unparalleled grip on wet and dry surfaces, despite encountering rough and rugged ground.The lace furniture allows the fit to be controlled with both a lace lock and tongue centralisation facility.Upper: Nubuck 1,6 mm, with SCARPA designLining - GORE-TEX Performance Comfort for a greater warm, comfort and waterproofnessSole: Bi-density sole with ex points to help boot reactivity on dynamic walkingPU insert in low density for shock-absorbing (1st injection) FLEX POINTS to help foot flexion and reactivity of dynamic walksMIDSOLE PU in medium density for more support and stability (2nd injection)PU in medium/high density for VIBRAM rubber outsole support and stability
