Alpinestars Tech 10 LE Air Gold Mens MX Offroad Boots

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.
