The Tech 10’s design is guided by three priorities; to improve overall functionality, performance and safety, decrease weight and reduce material volume. The result is a boot with a greater range of movement and flexibility while offering better control over the flexion and torsion forces that significantly improve boot performance, giving the rider greater confidence and protection. A breakthrough innovation for the Tech 10 is the introduction of Alpinestars patented Frontal Flex Frame. The complete and seamless flexion control system features an engineered frontal flexion control offered by a dual-density TPU connector system. The Tech 10 design is slimmer and more streamlined with a contoured calf protector ergonomically wrapping around the rear leg.
