The Alpinestars SMX-1 R V2 motorcycle boots are designed for riders seeking lightweight comfort, ventilation, and dependable protection for street and sport riding. This black and red model is offered in US size 5 / EU size 38 and features a microfiber upper for a durable, flexible fit. The tongue and rear accordion panels use lightweight padded materials to improve comfort while supporting natural movement on the motorcycle.
Airflow is enhanced through lateral air intakes with metallic mesh, while the Alpinestars speed lace system—derived from MotoGP technology—provides quick, precise, and secure closure. A higher closure system with an adjustable hook-and-loop fastening strap helps create a supportive fit. Protection includes foam-backed, double-density ankle disc protectors, lateral thermoplastic rubber guards, an external thermoplastic rubber toe reinforcement, and a thermoplastic polyurethane heel counter for impact and abrasion resistance. Internal toe reinforcement adds another layer of coverage beneath the microfiber upper.
A welded reflective rear insert improves rider visibility in low-light conditions. Inside, a breathable textile lining with anti-slip microfiber suede at the heel helps maintain foot positioning, while the removable anatomical EVA foam footbed supports everyday comfort. The exclusive Alpinestars vulcanized rubber compound sole provides traction and durability for street use. Manufacturer: Alpinestars. Vendor part number: 2224021-13-38.
