The Alpinestars SMX-1 R v2 Riding Boots are low-cut performance motorcycle boots designed for riders who want dependable protection, comfort, and control on and off the bike. This black pair is sized for US 7.5 / EU 41 and features a lightweight, abrasion-resistant microfiber upper reinforced with strategically positioned thermoplastic polyurethane (TPU) protectors. The ergonomic shape streamlines the forefoot while accommodating a broad range of foot profiles, helping provide a comfortable fit during daily rides, sport riding, and extended use.
The SMX-1 R v2 uses an anatomically angled hook-and-loop closure strap that follows the natural shape of the instep. A thermoplastic rubber puller and aramidic fiber reinforcement make the closure lightweight, durable, and easy to operate. The reverse zipper supports convenient entry and removal, while the heel counter support system works with the strap to improve fit, structure, and ankle support. Accordion flex zones at the instep and Achilles area, along with thermowelded flex grooves, promote controlled movement and flexibility when shifting, walking, or positioning the foot on the controls.
Protection features include double-density ankle protectors, an internal toe box, an external TPU heel counter, lateral ankle reinforcement, and a durable TPU shift pad. Alpinestars’ Transversal Protection Frame is integrated into the rubber compound sole to help protect against transversal loads. The sole also provides grip, water dispersion, and durability, while an integrated, replaceable bi-injected TPU forefoot slider uses an easy-screw fixing design for straightforward replacement. A removable anatomical footbed with EVA foam and Lycra, combined with an internal mesh lining, supports cushioning, cooling comfort, and moisture management. The Alpinestars SMX-1 R v2 Boots, manufacturer and vendor part number 2224521-10-41, fit riders seeking a protective low-profile boot for motorcycle street and performance applications.
