The Tech 10 is designed with three main priorities: to improve overall functionality, performance, and safety, while decreasing weight and reducing material volume. This results in a boot offering a greater range of movement and flexibility, providing better control over flexion and torsion forces. These improvements enhance boot performance, giving riders increased confidence and protection. A breakthrough innovation in the Tech 10 is the patented Frontal Flex Frame, a complete and seamless flexion control system featuring engineered frontal flexion control through a dual-density TPU connector system. The design of the Tech 10 is slimmer and more streamlined, with a contoured calf protector that ergonomically wraps around the rear leg.
