Alpinestars Tech 10 Supervented Boots — US 9, Over‑Calf, Purple

Experience race-derived protection with industry-leading ventilation in the Tech 10 Supervented Boots.

The boot combines a perforated microfiber upper and internal perforated padding with targeted TPU ventilation windows to maximize airflow while maintaining impact resistance. A redesigned shin plate and lateral calf vents work with two large front inlet ports and rear exhausts to promote continuous heat exchange and cooling.

The sole features a 3D higher spring insole with integrated air channels for active cooling and a proprietary dual-compound grip sculpturing that improves foot-peg contact, shifting feel and water and mud run-off. Central sole insert provides a replaceable micro-grip and side hooking design for prolonged performance.

Mechanical performance elements include a new double pivot motion control system with medial and lateral pivots, bi-density front flexion control, dual front blades and a shock absorber insert for progressive force release. The boot also integrates a patented Dynamic Heel Compression Protector (DHCP) to absorb impact energies and reduce transmitted forces to ankle and lower leg.

Comfort details include a 3D mesh lining with anti-sliding suede at the heel, a soft microfiber gaiter to seal out dirt and water, replaceable buckles with memory quick-release, and a perforated footbed for extra cooling and cushioning.
