The Alpinestars SMX-S Boot is a high-performance motorcycle riding boot designed for riders who want dependable protection, comfort, and precise fit. This black boot features a durable microfiber upper that provides flexibility while helping resist abrasion. Its ergonomic shape supports a natural riding position, while the highly refined last delivers a secure, precise fit for street and sport riding applications.
Protection: Double-injected polyurethane shields protect the shin, ankle, calf, toe, and heel from impacts while helping minimize abrasion. An additional inner protection panel is connected to the heel counter and extends along the outer ankle beneath the boot’s protective shell. A replaceable, bi-injected polyurethane toe slider uses a snap-in assembly for convenient maintenance and continued performance.
Comfort: The quick-drying polyamide lining is laminated with open-cell foam and contoured high-density padding to help absorb shocks around the foot. The breathable MTP mesh liner and removable anatomical polyurethane foam footbed help keep the foot cool and comfortable. Air vents at the ankle, heel, and forefoot are covered with specially designed mesh, while the wide instep and Achilles flex bellows support freedom of movement.
Fitment: An inner medial-side entry system uses an elastic-mounted zipper and extra-wide hook-and-loop flap for a secure, adjustable fit and easy access. The exclusive Alpinestars rubber compound sole incorporates structured shank reinforcement to support the arch and improve riding stability. This size 46 / US 11.5 boot is manufactured by Alpinestars and is identified by manufacturer and vendor part number 2223517-1100-46.
