Alpinestars SMX-S Motorcycle Boots - Black, US 8 / EU 42, Part Number 2223517-1100-42

The Alpinestars SMX-S Boots are engineered for rider comfort and maximum protection on the road. Featuring a durable microfiber upper, these boots provide a high level of flexibility while maintaining excellent durability. The microfiber construction is combined with advanced impact shields made from double injected polyurethane (PU) that safeguard the shin, ankle, calf, toe, and heel from impacts and abrasions. An inner double-injected panel connected to the heel counter offers additional protection, running up the outer ankle for comprehensive coverage. The quick-drying polyamide lining, laminated with open cell foam and high-density contoured padding, absorbs shocks and keeps the foot area comfortable during long rides. The structured rubber sole with an integrated shank reinforcement enhances support, especially in the arch area, contributing to better control and stability. The boots feature an interchangeable bi-injected PU toe slider with a snap-in assembly, allowing customization and added protection. Innovative air vents located at the ankle, heel, and forefoot are covered with specially designed mesh, providing unmatched ventilation that keeps the rider’s feet cool and dry. The large ‘throat’ profile, along with Achilles flex bellows, offers superior flex and comfort, accommodating natural foot movement. The MTP mesh liner and removable PU foam footbed further enhance breathability and comfort, making these boots suitable for extended riding sessions. An inner side entry system with elastic-mounted zipper and wide Velcro® flap ensures a precise, comfortable fit and easy access. The highly ergonomic last shape delivers an ultra-precise fit, reducing fatigue and enhancing control. Whether for sport or touring, the Alpinestars SMX-S Boots combine advanced protection, comfort, and style for riders demanding high performance.
