Engineered for OFF-ROAD riders, the Tech 10 Boots are Alpinestars’ flagship MX boots delivering precise control. Featuring Frontal Flex Frame, dual-pivot chassis, and biomechanical inner ankle brace with Dynamic Heel Compression Protector, proven in Supercross and Motocross, the boots are CE certified to EN 13634:2017. A lighter microfiber/TPU shell and cold-forged buckles trim over 400 g, improve fit and peg feel, and control flex to reduce hyperextension on demanding terrain.

Key features

Rear blade hyperextension control and Dynamic Heel Compression Protector (DHCP): dual-density TPU rear blade limits hyperextension while the patented collapsible heel with expanded poly‑foam absorbs high‑impact energy to reduce ankle and lower‑leg injury risk, proven in professional Supercross and Motocross use.
Bio-mechanical inner ankle brace: lighter, anatomically redesigned medial and lateral torsion arms increase range of motion and control; working with the outer boot chassis to deliver vertical and lateral protection with progressive damping of torsional forces while maintaining natural mobility.
Double pivot system: preserves chassis integrity through flex, eliminating the need for alternative torsion bars and providing progressive resistance to rotational and vertical forces to help protect ankles, knees, upper legs, and pelvis.
CE certification EN 13634:2017: independently validated protection performance.

Protection

Impact- and abrasion-resistant TPU shell for external protection.
Frontal Flex Frame with dual front and rear blade connectors creates a complete flexion control system from the foot shell to the shin plate, preventing over-compression and hyper-extension.
Dual-density TPU connector system ‘floats’ between lower and upper boot structures to distribute impact energy, control forward and rearward flex, and dampen shocks.
Asymmetrical dual pivot arms on the boot frame provide controlled articulation to help limit torsional loading.
Outer-shell ankle control system manages vertical compression and enhances impact protection while allowing natural ankle movement.
Asymmetrical medial and lateral double pivot system supports independent and synchronized movement for precise control of flexion forces.

Construction

Lightweight, wear‑resistant material composites; cold‑forged aluminum buckles with a self‑aligning closure geometry.
Streamlined boot architecture using integrated component construction and advanced bonding processes.
Chassis constructed from advanced lightweight microfiber paired with an impact‑ and abrasion‑resistant TPU shell.
Frontal Flex Frame with dual front and rear blade connectors; dual‑density TPU connector links the lower buckle plate, upper blade connector, buckle, and shin protector via a floating interface between lower and upper boot structures.
Asymmetrical, dual‑pivot arms integrated into the boot frame.
Outer‑shell ankle control system integrated within the shell construction.
Asymmetrical medial and lateral double‑pivot layout with a higher‑placed medial pivot arm and reduced inner‑side material volume to accommodate the inner ankle brace system.
