Alpinestars Supertech R Boots - Black - US 10.5 / EU 45 - Part 2220021-10-45

The Alpinestars Supertech R Boots are designed for high-performance motorcycle riders seeking superior protection and advanced comfort. Constructed with an innovative microfiber upper, these boots offer lightweight durability combined with excellent flexibility. The front flex zone, made from soft microfiber, enhances abrasion resistance while supporting natural forward and backward foot movement. Strategically placed ventilation areas in the heel and shin improve airflow, keeping your feet cooler during intense rides. The outside entry and exit feature a stretchable accordion panel that ensures a snug fit and effortless removal, while the contoured high modulus shin plate provides outstanding impact and abrasion resistance for critical protection.

The Supertech R integrates Alpinestars' evolution of the Multi-Link Control system, offering exceptional external control for ankle articulation. This system limits hyper-torsion, hyper-extension, and hyper-flexion movements, reducing injury risk while maintaining mobility. A dual-density TPU replaceable toe slider with a screw-in assembly offers added protection around the outer toe, enhancing durability in aggressive riding conditions. The wide heel counter, combined with lateral ventilation and a shock-absorbing padded insert, enhances support and comfort, with the self-molding ankle reinforcement providing additional impact absorption. Both the replaceable heel slider and external side heel slider are positioned to dissipate shock and facilitate sliding during falls.

Large asymmetrical accordion zones at the front and rear maximize flexibility, while an advanced synthetic lining laminated with open-cell foam ensures effective shock absorption and breathability. The micro-adjustable ratchet top closure allows for a secure fit, complemented by an inner instep speed lacing system and a lateral zipper for precise adjustments. The hook-and-loop tab locks the zipper in place, preventing accidental opening. The anatomically shaped and replaceable EVA footbed provides arch support and a forefoot pedal feel, enhancing rider control. The durable rubber sole features an even textured surface for consistent grip, essential for confident riding. The Alpinestars Lace-Lock System, made from advanced polymer resin, guarantees quick, secure closure, completing this high-performance riding boot designed for safety and comfort on the track or street.
