The Alpinestars SMX-S motorcycle boots combine a durable microfiber upper with advanced impact and abrasion protection for street and sport riding. Finished in black and sized for US 13.5 / EU 49, these boots feature an ergonomic last designed to provide a precise, supportive fit. The high-tech microfiber construction offers flexibility while maintaining the structure needed for confident control and long-lasting wear.
Protection is built into the SMX-S boot through double-injected polyurethane shields covering the shin, ankle, calf, toe, and heel. An additional inner protective panel is connected to the heel counter and positioned beneath the outer shell to reinforce the outer ankle area. A replaceable, bi-injected polyurethane toe slider uses a snap-in assembly, while the exclusive Alpinestars rubber compound sole includes structured shank reinforcement for enhanced arch support and foot stability.
Comfort and ventilation are supported by a quick-drying polyamide lining laminated with open-cell foam and contoured high-density padding to help absorb shocks around the foot. Mesh-covered air vents at the ankle, heel, and forefoot promote airflow, while the MTP mesh liner and removable anatomical polyurethane foam footbed help keep the foot cool during rides. The large throat-profile instep and Achilles flex bellows improve mobility without compromising support.
An innovative medial-side entry system uses an elastic-mounted zipper and extra-wide hook-and-loop flap for a secure, adjustable fit and easy access. The Alpinestars SMX-S boots are designed for motorcycle riders seeking a balance of protection, flexibility, ventilation, and everyday riding comfort.
