The Alpinestars SMX-S motorcycle boots combine a durable microfiber upper with advanced impact and abrasion protection for street and sport riding. Designed in black for a streamlined appearance, these boots feature an ergonomic last that supports a precise, comfortable fit in US 12 / EU 47. The quick-drying polyamide lining, open-cell foam, and contoured high-density padding help absorb shocks while maintaining comfort during extended rides.
Protection is built into the SMX-S model with double-injected polyurethane shields covering the shin, ankle, calf, toe, and heel. An additional inner protective panel connects to the heel counter and extends along the outer ankle beneath the outer shell. The exclusive Alpinestars rubber compound sole includes structured shank reinforcement to support the arch, while the interchangeable bi-injected polyurethane toe slider uses a convenient snap-in assembly.
Ventilation is provided through air vents at the ankle, heel, and forefoot, each covered with specially designed mesh to promote airflow and rider comfort. A medial-side entry system combines an elastic-mounted zipper with an extra-wide hook-and-loop flap for easy access and a secure, adjustable fit. The large throat-profile instep and Achilles flex bellows improve flexibility, while the MTP mesh liner and removable anatomical polyurethane foam footbed help keep feet cool and comfortable. The Alpinestars SMX-S Boots are manufactured by Alpinestars and identified by manufacturer and vendor part number 2223517-1100-47.
