Alpinestars Supertech R Motorcycle Boots - Red, US 9.5 / EU 44 - Part 2220021-3029-44

Designed for high-performance riding, the Alpinestars Supertech R boots feature an advanced microfiber upper construction that offers lightweight protection combined with exceptional flexibility. The front flex zone utilizes soft microfiber to enhance abrasion resistance while allowing natural forward and backward movement, ensuring comfort during intense riding sessions. Strategically placed ventilation areas in the heel and shin provide improved airflow, keeping your feet cool and dry on long rides. The stretchable accordion panels at the outside entry and exit points create a snug fit and facilitate easy donning and removal, making these boots user-friendly without compromising on support.
Constructed with a contoured high modulus shin plate, the Supertech R boots deliver superior impact and abrasion resistance, safeguarding critical areas during falls or collisions. The external ankle support, an evolution of Alpinestars' multi-link control system, offers advanced protection and support for ankle articulation, limiting hyper-torsion, hyper-extension, and hyper-flexion movements. This system also provides added Achilles impact protection. The dual-density TPU replaceable toe slider with a screw-in assembly offers reliable coverage around the outer toe, enhancing durability and safety. The wide heel counter, combined with lateral ventilation, extends to the ankle and includes a shock-absorbing padded insert and self-molding ankle reinforcement for comfort and stability.
Shock absorption and flexibility are further enhanced by large, asymmetrical accordion zones at the front and rear, optimized to maximize mobility. The synthetic forefoot lining, laminated with open cell foam, provides excellent shock absorption and breathability, maintaining comfort during prolonged use. The micro-adjustable ratchet top closure system ensures a secure fit, while the inner instep speed lacing closure and lateral zipper allow for precise adjustments and quick donning. The hook-and-loop tab keeps the zipper pull secure, maintaining a flat profile for safety.
The anatomically shaped and replaceable EVA footbed offers arch support and a firm pedal feeling, while the durable rubber sole provides consistent grip and improved riding feedback. The innovative Lace-Lock System, made from advanced polymer resin, guarantees a quick and secure closure, preventing slippage. Overall, the Alpinestars Supertech R boots combine advanced protection, intelligent ventilation, and superior comfort, making them ideal for competitive and serious riders seeking premium footwear.
