The Alpinestars SMX-S motorcycle boots are designed for riders who want dependable protection, comfort, and precise fit during street and sport riding. This black and white model features a durable microfiber upper that provides flexibility while helping resist abrasion. The ergonomic last, shaped forefoot, and large instep profile support a secure, comfortable fit for riders wearing a US 14 / EU 50 boot.
Protection: Double-injected polyurethane shields help protect the shin, ankle, calf, toe, and heel from impacts while minimizing abrasion. An additional internal protection panel connects to the heel counter and extends along the outer ankle beneath the external shell. The interchangeable bi-injected polyurethane toe slider uses a snap-in assembly for convenient replacement. Support: The exclusive rubber compound sole includes structured shank reinforcement to support the arch and promote stable footing.
Comfort: A quick-drying polyamide lining is laminated with open-cell foam and contoured high-density padding to help absorb shocks around the foot. Innovative vents at the ankle, heel, and forefoot are covered with purpose-designed mesh to promote airflow. A removable anatomical polyurethane foam footbed and MTP mesh liner help maintain a cooler, more comfortable interior. The medial-side entry system combines an elastic-mounted zipper with an extra-wide hook-and-loop flap for easy access and a precise closure.
Fitment: These Alpinestars SMX-S boots are intended for motorcycle riders seeking a protective street-riding boot with a flexible microfiber construction and ergonomic fit.
