The Alpinestars SMX-S Boots are performance-focused motorcycle riding boots designed for riders who want dependable protection, comfort, and precise fit. This black and white SMX-S model is sized for US 8 / EU 42 and features a durable microfiber upper that provides flexibility while helping resist abrasion. Alpinestars’ ergonomic last supports a secure, natural fit for street and sport riding applications.
Protection is built into 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 interchangeable bi-injected polyurethane toe slider uses a snap-in assembly for convenient replacement, while the structured-shank rubber sole reinforces the arch area for support and control.
Comfort features include a quick-drying polyamide lining laminated with open-cell foam and contoured high-density padding to help absorb impact around the foot. Air vents at the ankle, heel, and forefoot promote airflow through a specially designed mesh, while the MTP mesh liner and removable anatomical polyurethane foam footbed help maintain a cooler, more comfortable riding environment. Instep and Achilles flex bellows improve mobility without compromising the supportive boot structure.
The inner medial entry system combines an elastic-mounted zipper with an extra-wide hook-and-loop flap for a secure, adjustable closure and easier access. The exclusive Alpinestars rubber sole and high-tech microfiber construction make the SMX-S a versatile choice for motorcycle riders seeking everyday road performance and integrated protection.
