The Alpinestars Supertech R motorcycle boots are designed for high-performance street and track riding, combining advanced protection, flexible movement, and a precise fit. This black boot is sized for US 10.5 / EU 45 and features an advanced microfiber upper that provides lightweight protection, excellent abrasion resistance, and natural fore-and-aft flexibility. Thermoplastic polyurethane panels promote airflow, while strategically placed ventilation zones in the heel and shin help improve comfort during demanding rides.
Protection is built into every major impact area. A contoured high-modulus shin plate helps resist impact and abrasion, while the Alpinestars Multi-Link Control system supports ankle articulation and helps limit hyper-torsion, hyper-extension, and hyper-flexion. The system also provides Achilles impact protection. Replaceable dual-density TPU toe sliders, heel sliders, and an external side heel slider help protect vulnerable areas while promoting controlled sliding during an accident. A wide heel counter, shock-absorbing padded insert, and self-molding ankle reinforcement provide additional support around the ankle and heel.
Fitment and closure are precisely managed with the Alpinestars Lace-Lock System, inner instep speed lacing closure, lateral zipper, and hook-and-loop tab that secures the zipper pull. A micro-adjustable ratchet top closure helps create a secure upper-leg fit, while stretchable accordion panels at the entry and outside closure improve ease of entry and removal. Flexible accordion zones at the front, rear, and Achilles maximize movement without compromising support.
Comfort features include an advanced synthetic forefoot lining with open-cell foam for shock absorption, breathable lining through the ankle and leg, and an anatomical replaceable EVA footbed with arch support and enhanced pedal feel. The durable rubber sole is evenly textured for consistent grip and improved riding feedback.
