The Alpinestars SMX-S Motorcycle Boots are designed for riders seeking a precise fit, dependable protection, and everyday comfort. This black and white model is sized for US 7.5 / EU 41 and features a durable, high-tech microfiber upper that provides flexibility while helping resist abrasion. The ergonomic last, shaped forefoot, large instep profile, and Achilles flex bellows support natural movement and a comfortable riding position.
Protection is integrated throughout the boot with double-injected polyurethane shields covering the shin, ankle, calf, toe, and heel. A concealed inner protection panel connects to the heel counter and extends along the outer ankle for additional coverage. The Alpinestars SMX-S also includes an interchangeable, bi-injected polyurethane toe slider with a snap-in assembly for practical track and street use. Its exclusive rubber compound sole incorporates structured shank reinforcement to support the arch and provide stability while riding.
Comfort and ventilation are supported by innovative air vents at the ankle, heel, and forefoot, each protected by specially designed mesh. The quick-drying polyamide lining is laminated with open-cell foam and contoured high-density padding to help absorb impacts around the foot. An MTP mesh liner and anatomical, removable polyurethane foam footbed promote airflow and cushioning. The 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.
