The Alpinestars SMX-1 R v2 Riding Boots are low-cut performance motorcycle boots designed for riders who want lightweight comfort, dependable protection, and precise control on and off the bike. This black pair is sized for US 6.5 / EU 40 and features an abrasion-resistant microfiber upper reinforced with strategically positioned Thermoplastic Polyurethane (TPU) protectors. The ergonomic shape supports a wide range of foot profiles, while the streamlined forefoot design helps improve comfort and feel around the motorcycle’s controls.
Fit: The anatomically angled hook-and-loop closure follows the natural shape of the instep for a secure, adjustable fit. A reverse zipper simplifies entry and removal, while the heel counter support system works with the closure strap to improve stability and structural integrity. Accordion flex zones at the instep and Achilles area support natural movement, and thermowelded flex grooves help control flexibility at the instep, medial side, and rear of the boot. The soft Thermoplastic Rubber (TPR) insert at the heel supports ankle movement and comfort during riding.
Protection: Double-density ankle protection is layered beneath the upper, with an external TPU heel counter, lateral ankle protector, and TPU shift pad providing added durability in high-impact and high-wear areas. Internal toe protection and an integrated, replaceable bi-injected TPU forefoot slider help protect the foot during street and sport riding. The Alpinestars Transversal Protection Frame (TPF) is integrated into the compound rubber sole to help resist transversal loads.
Comfort and performance: The exclusive Alpinestars compound rubber sole uses grip patterning to promote traction, water dispersion, durability, and road feel. A removable anatomical footbed with EVA foam and Lycra® supports the foot, while the internal mesh lining provides moisture-wicking comfort. The rear flex window also functions as an air intake to encourage airflow. Manufacturer: Alpinestars. Vendor part number: 2224521-10-40.
