The Alpinestars SMX-S Boots in Black, US 14 / EU 50, are engineered for riders seeking dependable protection, comfort, and flexibility during sport and street riding. Manufactured by Alpinestars, these motorcycle boots feature a durable high-tech microfiber upper that supports a precise fit while allowing natural movement. The ergonomic last, large throat-profile instep, and Achilles flex bellows help improve comfort and mobility on the motorcycle.
Protection is integrated throughout the boot with double-injected polyurethane shields covering the shin, ankle, calf, toe, and heel. An additional internal protective panel connects to the heel counter and extends along the outer ankle beneath the outer shell. The interchangeable, bi-injected polyurethane toe slider uses a snap-in assembly for convenient replacement. These features provide impact and abrasion resistance while preserving the flexible feel required for riding.
Inside, a quick-drying polyamide lining is laminated with open-cell foam and contoured high-density padding to help absorb shocks around the foot. The MTP mesh liner and anatomical, removable polyurethane foam footbed promote airflow and all-day comfort. Innovative vents at the ankle, heel, and forefoot are covered with protective mesh, while the exclusive Alpinestars rubber compound sole includes structured shank reinforcement to support the arch.
The medial side entry system uses an elastic-mounted zipper and extra-wide hook-and-loop flap to provide a broad opening and a secure, adjustable closure. Designed to fit riders requiring a US 14 / EU 50 size, the Alpinestars SMX-S Boots are suitable for compatible motorcycle and motorsport riding applications.
