The Alpinestars SMX-S motorcycle boots combine a durable microfiber upper with advanced protective construction for street and sport riding. This black boot is sized for US 7.5 / EU 41 and features an ergonomic last designed to provide a precise, comfortable fit. The high-tech microfiber shell offers flexibility while helping resist abrasion during everyday riding.
Protection is provided by double-injected polyurethane shields covering the shin, ankle, calf, toe, and heel. An additional inner protection panel is concealed beneath the outer shell and extends along the outer ankle to the heel counter. The interchangeable, bi-injected polyurethane toe slider uses a snap-in assembly for convenient replacement. The structured rubber sole includes shank reinforcement to support the arch and enhance control on the motorcycle.
Comfort-focused 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 mesh-covered openings, while the MTP mesh liner and removable anatomical polyurethane foam footbed help keep the foot cool. Flex bellows at the instep and Achilles area allow natural movement, and the medial-side entry system uses an elastic-mounted zipper with a wide hook-and-loop flap for easy access and a secure fit.
Designed by Alpinestars and manufactured for riders seeking dependable protection and comfort, the SMX-S boots provide coverage and support for street and sport motorcycle applications.
