These modern trekking boots feature a sole with the innovative TPU frame, ensuring outstanding torsional rigidity between the midfoot and ankle, and runs down to the heel area to permit the use of soft PU foam. The PU foam provides optimal cushioning and comfort in critical areas, allowing you to hike longer in unforgiving terrain. The Alverstone II GTX’s upper is constructed from Perwanger leather with Flex-Zones, and the lower sections feature Lateral Flex Technology; together, these features deliver excellent stability, and allows the boot to move in sync with the lower leg. Other features of the Alverstone II GTX include a Vibram Integral-Light sole with 3D PrismBase technology. This gives the boots excellent traction across a wide assortment of terrain, especially on steep uphill ascents thanks to a dedicated “climbing zone” built into the toe area. In addition, the Alverstone II GTX feature Click Clamps to enable precise lacing adjustment, and Two-Zone lacing allows the boots to be tighter at the bottom and looser at the top.
