Alpinestars Supertech R Boots - Black, White & Red - US 9.5 / EU 44, Part Number 2220021-123-44

The Alpinestars Supertech R Boots are engineered for high-performance motorcycle riding, combining lightweight microfiber construction with advanced protective features. The microfiber upper offers excellent abrasion resistance and natural flexibility, especially in the front flex zone designed for smooth forward and backward movement. Strategically placed ventilation areas in the heel and shin enhance airflow, keeping the rider comfortable during extended rides. The stretchable accordion panels at the outside entry and exit points ensure a snug fit and effortless donning and doffing, while the contoured high-modulus shin plate provides superior impact and abrasion protection for critical areas.
The boots incorporate Alpinestars' innovative Multi-Link Control system, offering enhanced external support and ankle articulation while limiting hyper-torsion, hyper-extension, and hyper-flexion movements. This system also provides effective Achilles impact protection. The dual-density TPU replaceable toe slider with a screw-in assembly safeguards the outer toe area against damage, ensuring durability. The wide heel counter, combined with lateral ventilation and a shock-absorbing padded insert, offers additional support and comfort. External heel sliders are strategically positioned to dissipate and absorb shocks, promoting slide during accidents and reducing injury risk.
Large asymmetrical accordion zones at the front and rear maximize flexibility, allowing natural foot movement. The synthetic forefoot lining laminated with open-cell foam absorbs shocks and maintains breathability, complemented by highly breathable ankle and leg linings for enhanced comfort. The micro-adjustable ratchet top closure, along with the interior speed lacing system and lateral zipper, provides a secure and precise fit. A hook-and-loop tab locks the zipper in place for safety.
The anatomically shaped, replaceable EVA footbed offers arch support and a close pedal feel, improving rider control. The durable rubber sole features an evenly textured surface for consistent grip and improved riding feel. The innovative Lace-Lock System, made from advanced polymer resin, ensures quick, secure closure, while the self-molding ankle reinforcement adds extra protection. Overall, the Alpinestars Supertech R Boots deliver a combination of lightweight performance, advanced protection, and rider comfort, making them ideal for competitive and serious street riders alike.
