Alpinestars SMX-S Motorcycle Boots - Black, US 7.5 / EU 41 - Part Number 2223517-1100-41

The Alpinestars SMX-S Boots are engineered for riders seeking premium protection combined with superior comfort. Crafted with a durable microfiber upper, these boots offer excellent flexibility and a snug fit, ensuring optimal control during rides. The high-tech micro-fiber construction enhances durability while maintaining lightweight performance. Integrated impact shields made of double injected polyurethane (PU) protect critical areas such as the shin, ankle, calf, toe, and heel, effectively absorbing shocks and minimizing abrasion risks. An inner protective panel, connected seamlessly to the heel counter and hidden beneath the outer shell, provides added impact resistance for enhanced safety.

Designed for comfort and breathability, the SMX-S features a quick-drying polyamide lining laminated with open cell foam and high-density contoured padding. This combination absorbs shocks and keeps the foot cool during extended rides. The exclusive rubber sole with structured shank reinforcement offers superior support, especially in the arch area, promoting rider stability. The boots include an interchangeable bi-injected PU toe slider with a snap-in assembly, allowing for customization and extended footwear lifespan. Innovative air vents located at the ankle, heel, and forefoot, covered with specially designed mesh, provide unmatched ventilation for all-day riding comfort.

A large ‘throat’ profile instep and Achilles flex bellows deliver superior flex and comfort, accommodating natural foot movement. The MTP mesh liner paired with an anatomical, removable PU foam footbed further enhances breathability and comfort, ensuring your feet stay cool and dry. The inner side entry system features an elastic-mounted zipper with a wide Velcro® flap, offering a precise fit and making access quick and easy. The highly ergonomic last shape ensures an ultra-precise fit, making the Alpinestars SMX-S Boots a reliable choice for serious motorcyclists who demand safety, comfort, and performance from their riding gear.
