The Alpinestars Supertech R motorcycle boots deliver advanced protection, precise fit, and flexible performance for sport and track riding. This red boot is sized for US 9 / EU 43 and features an advanced microfiber upper that helps reduce weight while providing dependable abrasion resistance and natural flexibility. The front flex area, Achilles zone, and asymmetrical accordion panels support comfortable forward, backward, and lateral movement without compromising protective coverage.
Protection is provided by a contoured high-modulus shin plate, thermoplastic polyurethane components, replaceable toe and heel sliders, and Alpinestars Multi-Link Control system. The external ankle support system helps limit hyper-torsion, hyper-extension, and hyper-flexion while also contributing to Achilles protection. A wide heel counter with lateral ventilation, shock-absorbing padding, and self-molding ankle reinforcement enhance impact management and support around the foot and ankle.
Fitment and comfort are refined through the Alpinestars Lace-Lock System, inner instep speed lacing closure, lateral zipper, and hook-and-loop zip-pull retainer. The micro-adjustable ratchet top closure provides a secure fit around the calf, while the anatomical, replaceable EVA footbed supports the arch and maintains pedal feel. Breathable lining in the ankle and leg areas, strategically positioned heel and shin ventilation, and an open-cell foam-laminated forefoot lining help improve comfort during extended use. The durable textured rubber sole promotes consistent grip and riding control. Manufactured by Alpinestars and supplied under vendor part number 2220021-3029-43.
