Alpinestars Supertech R Boots - Black/White/Red US 11.5 / EU 46 - Part 2220021-123-46

The Alpinestars Supertech R Boots are designed for high-performance motorcycle riding, combining advanced materials and innovative features to deliver superior protection, comfort, and flexibility. Constructed with an advanced microfiber upper, these boots provide lightweight durability and excellent abrasion resistance, ensuring they can withstand the rigors of aggressive riding. The front flex zone utilizes soft microfiber to enhance natural movement, giving riders better control and response during dynamic maneuvers. Strategically placed ventilation areas in the heel and shin promote airflow, helping to keep your feet cool and dry on long rides or intense sessions.
A flexible accordion microfiber on the Achilles area allows for natural movement, while the wide heel counter with lateral ventilation extends to the ankle, offering added support and breathability. The contoured high modulus shin plate protector provides exceptional impact and abrasion resistance, safeguarding critical areas against impacts and sliding falls. The external ankle support system, derived from Alpinestars' unique Multi-Link Control system, offers advanced protection and articulation, limiting hyper-torsion, hyper-extension, and hyper-flexion, and providing impact absorption around the Achilles.
The dual-density TPU replaceable toe slider with screw-in assembly delivers reliable protection for the outer toe area, ideal for aggressive riding and cornering. The large, asymmetrical accordion zones at the front and rear optimize flexibility, allowing for unrestricted movement while maintaining support. The inner lining features advanced synthetic materials laminated with open-cell foam, providing shock absorption and breathability in key contact areas for superior comfort. Micro-adjustable ratchet top closures and a lateral zipper ensure a precise, secure fit, while hook-and-loop tabs keep zippers flat and safe during rides.
The anatomically shaped EVA footbed is replaceable and offers excellent arch support and a natural pedal feel, enhancing rider control. The durable rubber sole is textured for consistent grip, contributing to better riding feel and safety. Additional protective features include a quick-close Lace-Lock System made from advanced polymer resin and self-molding ankle reinforcements, which work together to provide a secure fit and superior ankle stability. With replaceable heel sliders positioned to dissipate shock and facilitate sliding during falls, these boots combine safety with high-performance technology for serious riders.
