The Alpinestars SMX-S motorcycle boots combine a durable microfiber upper with advanced protection, ergonomic shaping, and rider-focused comfort. Finished in black and white, these boots are designed for street and sport riding and provide a precise fit through an ergonomic last, a wide-opening side-entry closure, and an elastic-mounted zipper secured by an extra-wide hook-and-loop flap. The Alpinestars SMX-S boots are sized for US 12.5 and EU 48 and are supplied under manufacturer and vendor part number 2223517-12-48.
Protection: Double-injected polyurethane shields the shin, ankle, calf, toe, and heel against impact while helping reduce abrasion. Inner protection is provided by a reinforced panel connected to the heel counter and positioned beneath the outer shell along the outer ankle. A replaceable bi-injected polyurethane toe slider uses a secure snap-in assembly for convenient service and continued protection.
Comfort: A quick-drying polyamide lining, open-cell foam, and high-density contoured padding help absorb shocks around the foot. The MTP mesh liner and anatomical, removable polyurethane foam footbed promote airflow and cushioning, while ventilation openings at the ankle, heel, and forefoot are protected by specially designed mesh. The large throat profile, instep, and Achilles flex bellows support natural movement and improved comfort while riding.
Support: Alpinestars' exclusive rubber compound sole includes structured shank reinforcement to support the arch and enhance control. The SMX-S boot's durable, flexible construction balances protection and mobility, making it a practical choice for riders seeking dependable street and sport motorcycle footwear.
