The Alpinestars Supertech R Boots are high-performance motorcycle riding boots designed for sport and track applications. This black model is sized US 9.5 / EU 44 and is manufactured by Alpinestars under manufacturer and vendor part number 2220021-10-44. The advanced microfiber upper combines lightweight construction, abrasion resistance, and flexibility for precise movement on the motorcycle. Soft microfiber flex zones at the front, Achilles, and accordion areas support natural forward and backward movement while maintaining protective coverage.
Protection is provided by a contoured high-modulus shin plate, external ankle support, and Alpinestars’ Multi-Link Control System. This system helps limit hyper-torsion, hyper-extension, and hyper-flexion while adding Achilles impact protection. Replaceable TPU toe and heel sliders help protect key contact areas and are designed to dissipate impact and encourage controlled sliding during an accident. A wide heel counter, shock-absorbing padded insert, self-molding ankle reinforcement, and strategically placed ventilation areas provide additional support, airflow, and comfort.
The Supertech R includes an Alpinestars Lace-Lock System, inner instep speed lacing, and a lateral zipper for a secure, micro-adjustable fit. A hook-and-loop tab secures the zipper pull in place, while the ratchet top closure stores its strap end neatly. The anatomical replaceable EVA footbed provides arch support and pedal feel, and the durable rubber sole delivers consistent grip. The boot’s breathable lining, open-cell foam forefoot construction, and flexible external panels make it suitable for riders seeking race-oriented protection and responsive control on compatible sport motorcycles.
