The Alpinestars Supertech R Boots are high-performance motorcycle riding boots designed for advanced protection, precise fit, and responsive control on the track or street. This black, white, and red model is sized US 10.5 / EU 45 and is identified by manufacturer and vendor part number 2220021-123-45. The advanced microfiber upper provides lightweight flexibility, while reinforced front flex areas and accordion zones support natural forward, backward, and lateral movement.
Protection is provided by a contoured high-modulus shin plate, dual-density TPU toe slider, replaceable heel slider, external side heel slider, and reinforced ankle construction. Alpinestars Multi-Link Control system helps limit hyper-torsion, hyper-extension, and hyper-flexion while supporting ankle articulation and Achilles protection. Ventilation zones in the heel and shin, breathable TPU components, and moisture-managing internal materials promote airflow and comfort during demanding rides.
The Alpinestars Lace-Lock System, inner instep speed lacing closure, and lateral zipper create a secure, adjustable fit. A micro-adjustable ratchet top closure and hook-and-loop tab help keep the closure system flat and secure. The anatomical replaceable EVA footbed provides arch support and pedal feedback, while the durable textured rubber sole delivers consistent grip and riding feel. The Supertech R Boots fit riders seeking race-inspired protection, mobility, and replaceable protective components in a premium motorcycle boot.
