The Tech 10’s design is guided by three priorities; to improve overall functionality, performance and safety, decrease weight and reduce material volume. The result is a boot with a greater range of movement and flexibility while offering better control over the flexion and torsion forces that significantly improve boot performance, giving the rider greater confidence and protection.

Fits small. We recommend ordering a size larger.

Key Features

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 not only easier to operate, more durable, and provide a self-aligning closure that offers a positive hold across the upper surfaces of the boot, this evolution has resulted in an impressive reduction in weight of over 400 grams (almost 1lb) for the MX25 Tech 10 Boots.
The new streamlined boot design also reduces the Tech 10’s profile and physical size. By incorporating the newer, lighter, and more durable composite materials and using a more integrated approach to the construction of the components, we’ve been able to dynamically enhance the chassis of the boot as well as use more advanced bonding processes.
The Tech 10 chassis combines advanced lightweight microfiber and with an impact and abrasion resistant TPU shell.
Combining with the dual front and rear blade connectors, the Frontal Flex Frame gives the Tech 10 a complete and seamless flexion control system, from the foot shell all the way up to the shin plate, offering high performance double motion control, preventing over-compression and hyper-extension, featuring:
Engineered frontal flexion control is offered by a dual-density TPU connector system, uniting the lower buckle plate with the upper blade connector, buckle and shin protector. Engineered to ‘float’ freely between the lower and upper boot construction, the Frontal Flex Frame acts as a shock absorber by distributing energy across the boot frame while controlling forward and rearward flex, progressively releasing force which dampens and absorbs impact energies.
Asymmetrical, dual pivot arms on boot frame.
A unique feature of the Tech 10 is the ankle control system developed in the outer shell construction, allowing natural ankle movement, vertical compression control and improved impact protection.
Asymmetrical medial and lateral double pivot system for improved levels of flexibility and precision for both independent and synchronized movement. The medial pivot arm’s higher placement reduces material volume in the lower part of the boot, creating more space for the patented inner ankle brace system to have free movement and improve control. Reducing the volume on the inner side also reduces abrasion, where the boot is in contact with the bike and improves grip and feel.

Construction

Low-profile, pull-on design for reduced material build, less weight and to facilitate easier and quicker wearing.
Innovative flexion inserts work seamlessly with the Tech 10’s flex support system for ultimate in performance.
TPU protection and shock absorbing padding on the heel and ankles and an ultra-thin and flexible forefoot area for increased sensitivity and control.
Dual compound removable anatomic footbed includes EVA for comfort and support and aids even weight distribution.
Sole with proprietary grip sculpturing delivers superior foot-peg performance, grip and mud and water run-off.
The central sole insert features micro grip and side hooking grip design. It is easily replaceable and Alpinestars offers a full sole replacement and boot repair service.
Triple buckle closure system features a nylon and fiberglass compound for improved durability and strength, and the slim-line buckles include high-impact bridge closures which are cold forged for precision and strength.
The 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. All buckles are easily replaceable.
Frontal protection features a dual closure system with an internal microfiber flap, plus hook and loop fasteners for a precise fit closure beneath the buckle giving greater, micro-adjustable precision which is convenient to operate.
Soft microfiber gaiter helps seal out excessive water and dirt entry.
Poly-fabric lining with 3D open cell foam incorporates anti-slip suede in heel area, keeping the foot located inside the boot.

Protection

Dual density TPU rear blade system engineered to prevent hyperextension while offering improved flex control and impact resistance. Built into the Tech 10’s unique and lightweight single-piece co-injected foot chassis is the patented 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. DCHP features a directional impact protection system which significantly reduces the effect of excessive, potentially injury-causing, energy being transferred to the ankle and lower leg. DHCP has been used by Alpinestars’ athletes in the demanding environments of professional Supercross and Motocross.
The bio-mechanical inner ankle brace features lighter, anatomically redesigned medial and lateral torsion arms which are compact and offer increased range of movement and control. In conjunction with the outer boot chassis, the ankle brace gives vertical and lateral protection from ankle and leg compression and rotation and progressive damping of torsional forces during an accident, while still allowing natural freedom of movement.
A double pivot system allows the Tech 10 to retain its integrity while flexing which removes the need for alternative torsion bars for varying ankle widths and crucially gives the essential progressive resistance to rotational and vertical forces which, otherwise, may be damaging to ankles, knees, upper legs and pelvis if not arrested in a controlled way.
