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 and white pair is sized for US 6.5 / EU 40 and features a lightweight, abrasion-resistant microfiber upper reinforced with strategically positioned Thermoplastic Polyurethane (TPU) protectors. The ergonomic shape supports a broad range of foot profiles while helping provide a streamlined fit around the forefoot.
Designed for street riding, commuting, and sport-oriented use, the SMX-1 R V2 combines flexible construction with protective reinforcement in key impact and abrasion areas. Accordion flex zones at the instep and Achilles support natural movement, while thermowelded flex grooves help control flexibility at the instep, medial side, and rear of the boot. The reverse zipper and anatomically angled hook-and-loop closure strap provide convenient entry and a secure fit over the instep. A TPR puller and aramidic fiber wires contribute to easy operation and durable, low-profile closure performance.
The exclusive Alpinestars compound rubber sole delivers grip, water dispersion, and durability, with an integrated Alpinestars Transversal Protection Frame (TPF) to help manage transversal loads. External TPU protection is provided at the heel counter, lateral ankle, and shift area, while double-density ankle protectors and internal toe box reinforcement add coverage beneath the upper. The replaceable bi-injected TPU forefoot slider uses an easy-screw fixing concept for efficient replacement. A removable anatomical footbed with EVA foam and Lycra supports comfort, and the internal mesh lining helps promote cooling, moisture-wicking airflow. The rear flex bellow includes a ventilation window for added airflow during riding. Manufactured by Alpinestars and identified by manufacturer and vendor part number 2224521-12-40.
