The Alpinestars SMX-S motorcycle boots combine a durable microfiber upper with advanced protection and rider-focused comfort. Designed in a black finish for a clean, versatile look, these boots feature an ergonomic last that supports a precise fit and a shaped forefoot for improved control. This model is sized US 9.5 / EU 44 and is manufactured by Alpinestars under manufacturer and vendor part number 2223517-1100-44.
Protection: Double-injected polyurethane shields the shin, ankle, calf, toe, and heel against impact while helping minimize abrasion. A concealed double-injected panel beneath the outer shell extends along the outer ankle and connects to the heel counter for additional support. The interchangeable bi-injected polyurethane toe slider uses a convenient snap-in assembly for easy replacement.
Comfort: A quick-drying polyamide lining is laminated with open-cell foam and high-density contoured padding to help absorb shocks around the foot. The MTP mesh liner and anatomical removable polyurethane foam footbed promote airflow and all-day comfort. Air vents at the ankle, heel, and forefoot are covered with protective mesh, while the large throat profile instep and Achilles flex bellows improve movement. An elastic-mounted zipper with an extra-wide hook-and-loop flap provides a secure medial-side closure and a wide opening for easier access.
Performance: The exclusive Alpinestars rubber compound sole includes structured shank reinforcement to support the arch and deliver dependable stability. The SMX-S boots are suited for street and sport motorcycle riding, offering a balance of flexibility, impact protection, ventilation, and precise fit for riders seeking dependable footwear performance.
