The Alpinestars 2021 Motocross Protection Collection has been designed with the utmost attention to materials technology, maximum airflow and ultimate protection and performance.  Engineered to protect riders, the new 2021 line expands the range with the addition of two important products: the SM5 helmet and the Tech 10 Supervented boot, bringing leading ventilation technology to both the helmet and the boot. The Tech 10 Supervented is pioneering the way for improving performance and rider comfort by dissipating heat significantly in the boot through increased airflow across the entire bottom of the foot. The benchmark in Motocross footwear, Alpinestars’ Tech 10 boot is extending the line with the new Supervented version offering a unique patented construction that streams cool air into the boot throughout the bottom of the foot; further advancing the innovations that make it the most technical motocross boot in history.  Laboratory tests have shown that the Tech 10 Supervented boot dissipates heat 34% faster than a non-vented boot. This technology uses 3D open channels from front to back, in combination with a ventilated ankle brace to promote maximum airflow.
  • Highly breathable, perforated microfiber.
  • TPU features is combined with ventilation zones and a new air flow system sole for breathability and superior ventilation.
  • Two large inlet ports on front of boot with exhausts at back for optimized levels of airflow and heat exchange.
  • Co-injected for strength and structure, the exclusive TPU and rubber compound panels provide superb levels of grip contact, durability and heat resistance.
  • The contoured calf protector ergonomically wraps around the rear leg and is constructed from a dual density compound rear blade system to offer progressive dampening of excessive torsional forces.
  • Shin plate features a new anatomic design for reduced surface area and weight-saving.
  • Completely re-designed sole with proprietary grip sculpturing to improve foot-peg performance, grip and mud and water run-off. Exclusive dual compound sole is seamlessly integrated to the multi-density foot base structure with built-in support. The sole offers superior durability, grip and feel while riding, and improved performance on the shifter.
  • Innovative, lightweight upper combines advanced lightweight microfiber with an impact and abrasion resistant TPU shell.
  • The foot shell features five different compounds in a single lightweight piece to offer strength while maintaining flexibility and structural integrity: heel and toe protection (highly resistant against abrasion and impact while adding to the boot’s overall durability) & shank (support and structural integrity).
  • Frontal protection features a dual closure system with an internal microfiber flap, plus hook and loop fasteners for a precise fit closure attached securely with a micro-adjustable, easy to operate, lightweight buckle.
  • The shin: unique TPU blade system engineered to prevent frontal hyper-extension and offer greater flex control.
  • Soft microfiber gaiter helps seal out excessive water and dirt entry, while the 3D mesh lining ensures improved air circulation and comfort.
  • 3D mesh lining: anti-sliding suede on heel area (keeps the foot located inside the boot)
  • Highly ventilated perforated padding for optimized ventilation and airflow.
  • Perforated footbed for additional cooling.
  • Central sole insert: micro grip and side hooking grip design (easily replaceable and Alpinestars offers a full sole replacement and boot repair service)
  • Mesh construction for optimal levels of airflow inside the boot
  • New mechanical buckle closure system: nylon & fiberglass compound (improved durability and strength.
  • New slim-line buckle closure system: high-impact bridge closures (cold forged for precision and strength) & memory and quick release/locking system (easy, precised closure and improved riding performance and security)
  • All buckles are easily replaceable
  • Air vents on the PU lateral calf & breathable mesh: improve comfort and reduce fatigue on short and long rides
  • 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 polyfoam 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 developed and tested in the demanding circuits of professional Supercross and Motocross.
  • New performance double pivot motion control system features: medial and lateral double pivot system for improved levels of flexibility and precision control & engineered bi-density front flexion control is strategically positioned over the mesh area, combined with a dual front blade system and shock absorber insert to offer mechanical progressive force release to dampen and absorb impact energies & re-designed dual density TPU rear blade system is engineered to prevent hyper-extension while offering improved flex control and impact resistance.
  • Evolutionary new shin plate design with ventilation windows strategically positioned to allow more ventilation without compromising the impact protection.
  • 3D Higher Spring insole creates an effective cooling system using air channels within the sole for optimal levels of ventilation, while also creating a cushioning effect for enhanced levels of comfort.
  • According to European statutory law the CE mark is a conformity requirement for the marketing of this product. The following standards apply: CE EN13634.
