The Alpinestars Supertech R Boots combine advanced microfiber construction with protective TPU components for lightweight performance, flexibility, and abrasion resistance. The soft microfiber front flex area and large asymmetrical accordion zones support natural forward-and-back movement, while strategically positioned ventilation areas in the heel and shin promote airflow.

An evolution of Alpinestars’ Multi-Link Control system provides external ankle protection and support while helping limit hyper-torsion, hyper-extension, and hyper-flexion. The contoured high-modulus shin plate, replaceable toe slider, heel slider, and external side heel slider provide protective coverage and are designed to help dissipate and absorb impact.

The boots feature a wide heel counter with lateral ventilation, shock-absorbing padded inserts, self-molding ankle reinforcement, and flexible accordion microfiber at the Achilles. An advanced synthetic forefoot lining with open-cell foam supports shock absorption, while breathable ankle and leg linings enhance comfort.

Fit and closure features include the Alpinestars Lace-Lock System, inner instep speed lacing closure, lateral zipper, micro-adjustable ratchet top closure, and hook-and-loop tab that secures the zipper pull. An anatomical replaceable EVA footbed provides arch support and forefoot pedal feel, while the durable rubber sole delivers consistent grip and riding feel.
