The Alpinestars SMX-S Boot is a performance-focused motorcycle boot designed for riders seeking dependable protection, comfort, and precise fit. This black and white boot is sized at US 13.5 / EU 49 and features a durable, high-tech microfiber upper that provides flexibility while helping resist abrasion. Its ergonomic last supports an accurate fit, while the shaped forefoot, large throat-profile instep, and Achilles flex bellows promote natural movement and riding comfort.
Protection is built into the SMX-S through double-injected polyurethane shields covering the shin, ankle, calf, toe, and heel. An additional inner protection panel is connected to the heel counter and positioned beneath the outer shell along the medial ankle for added impact coverage. The interchangeable bi-injected polyurethane toe slider uses a snap-in assembly, allowing convenient replacement when needed. Alpinestars’ exclusive rubber compound sole includes structured shank reinforcement to support the arch and improve overall riding stability.
Ventilation and interior comfort are supported by air vents at the ankle, heel, and forefoot, each covered with purpose-designed mesh. The quick-drying polyamide lining is laminated with open-cell foam and contoured high-density padding to help absorb shocks around the foot. An MTP mesh liner and anatomical, removable polyurethane foam footbed help keep the foot comfortable during extended rides. The medial side entry system combines an elastic-mounted zipper with an extra-wide hook-and-loop flap for a secure, adjustable closure and easy access.
