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. The Tech 10 features Alpinestars patented Frontal Flex Frame, a complete and seamless flexion control system with engineered frontal flexion control offered by a dual-density TPU connector system. The design is slimmer and more streamlined with a contoured calf protector ergonomically wrapping around the rear leg.
