The Alpinestars Tech 10 boots are engineered for ultimate functionality, performance, and safety, with a focus on reducing weight and material volume. This results in a boot that offers an enhanced range of movement and flexibility, providing superior control over flexion and torsion forces for improved performance. The boot features Alpinestars' patented Frontal Flex Frame, a complete and seamless flexion control system with dual-density TPU connectors for engineered frontal flexion control. The design is slimmer and more streamlined, with an ergonomically contoured calf protector that wraps around the rear leg. This specific variant is a size 13 UK.
