The most significant upgrades to the Tech 10 performance are unique technologies: The Frontal Flexion Control Frame, the Asymmetrical Dual-pivot Arms, the patented Dynamic Heel Compression Protection Shock Absorber which is integrated into a redesigned foot shell and the slimmer, more streamlined, outsole., New material composites have been created that are lighter in weight and more durable to ensure they hold up to the rigors of off-road riding. The new, cold-forged, aluminum buckles are a result with an easier to operate, more durable and self-aligning closure that offer a positive hold across the upper surfaces of the boot. The result has yielded over 400 grams (almost 1lb) in weight reduction for the new Tech 10., The design also reduces the Tech 10’s profile and physical size. It is more streamlined with newer, lighter, more durable composite materials and a more integrated approach to the construction of the components which dynamically enhance the chassis of the boot and utilize more advanced bonding processes., Asymmetrical medial and lateral double pivot system for improved levels of flexibility and precision for both independent and synchronized movement, Constructed from a dual density compound and combined with the rear blade system, Double pivot system allows the Tech 10 to retain its integrity while flexing, Energy dissipating shin plate features a new anatomic design for reduced surface area and weight-saving, Exclusive dual-compound sole is seamlessly integrated to the multi-density foot base structure with built-in support, Foot shell features five different compounds in a single lightweight piece to offer strength while maintaining flexibility and structural integrity, Innovative flexion inserts work seamlessly with new flex support system for ultimate in performance, Low-profile, pull-on design for reduce material build, less weight and to facilitate easier and quicker wearing, Poly-fabric lining with 3D open cell foam incorporates anti-slip suede in heel area, keeping the foot located inside the boot, Provides a complete and seamless flexion control system, from the foot shell all the way up to the shin plate, Redesigned dual density Thermoplastic Polyurethane (TPU) rear blade system engineered to prevent hyper-extension while offering improved flex control and impact resistance, TPU protection and shock absorbing padding on the heel and ankles, Ankle control system developed in the outer shell construction, allowing natural ankle movement, vertical compression control and improved impact protection, Asymmetrical, dual pivot arms on boot frame, Chassis combines advanced lightweight microfiber and impact and abrasion resistant TPU shell, Closure system features contra-closure, doubling closure security and a quick release/locking system with self-aligning, memory, design for easy, precise closure and improved riding performance and security, Combines dual front and rear blade connectors, Completely redesigned sole with proprietary grip sculpturing to improve foot-peg performance, grip and mud and water run-off, Contoured TPU calf protector plate offers impact resistance, Dynamic Heel Compression Protector (DHCP), an innovative safety feature which includes a fully integrated collapsible heel area with expanded poly-foam to absorb high impact energies during a crash, Engineered to 'float' freely between the lower and upper boot construction
