The Alpinestars Supertech R motorcycle boots deliver advanced protection, flexibility, and rider-focused control for high-performance street and track riding. This red model is sized at US 11.5 / EU 46 and features an advanced microfiber upper for lightweight comfort and abrasion resistance. Strategically positioned ventilation zones in the heel and shin promote airflow, while flexible accordion panels at the front, rear, Achilles, and entry area support natural movement and provide a close, secure fit.
Protection is provided by a contoured high-modulus shin plate, Thermoplastic Polyurethane (TPU) reinforcement, and Alpinestars Multi-Link Control System. This external ankle protection system helps limit hyper-torsion, hyper-extension, and hyper-flexion while also helping protect the Achilles area during an impact. Dual-density TPU replaceable toe sliders, a replaceable heel slider, and an external side heel slider help dissipate impact energy and encourage controlled sliding in an accident. A wide ventilated heel counter, shock-absorbing padded insert, and self-molding ankle reinforcement add support around the foot and ankle.
Fit and closure features include the Alpinestars Lace-Lock System, an inner instep speed-lacing closure, a lateral zipper, and a hook-and-loop tab that secures the zipper pull. The micro-adjustable ratchet top closure stores the tab end for a streamlined finish. Inside, the advanced synthetic forefoot lining uses open-cell foam for shock absorption, while breathable materials in the ankle and leg areas improve comfort during extended riding. The anatomical, replaceable contoured EVA footbed provides arch support and pedal feel, and the durable rubber sole delivers consistent grip through an evenly textured surface.
