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

The Alpinestars SMX-S Boots are engineered for riders seeking superior protection, comfort, and performance. Crafted with a durable microfiber upper, these boots provide a flexible yet resilient fit that adapts to your foot for enhanced control and comfort during long rides or aggressive maneuvers. The innovative construction incorporates high-tech micro-fiber material that ensures longevity and a lightweight feel, making them a reliable choice for everyday riding or competitive events. The ergonomic forefoot shaping and large instep profile promote natural movement, reducing fatigue and increasing rider confidence.
The SMX-S features double-injected polyurethane shields over the shin, ankle, calf, toe, and heel areas, offering impact resistance and abrasion protection where it matters most. An inner protection panel connected to the heel counter adds an extra layer of defense, seamlessly integrated beneath the outer shell. The quick-drying polyamide lining, laminated with open-cell foam and contoured padding, absorbs shocks and wicks moisture away, maintaining comfort in diverse riding conditions.
For support and stability, the boots are equipped with an exclusive rubber compound sole reinforced with a structured shank that provides arch support and enhances pedal control. The interchangeable bi-injected PU toe slider with a snap-in assembly allows customization and added durability in high-wear areas. To improve rider comfort, innovative air vents at the ankle, heel, and forefoot are covered with specially designed mesh, ensuring optimal airflow and temperature regulation. The large ‘throat’ profile, Achilles flex bellows, and MTP mesh liner contribute to superior flexibility and fit, accommodating a range of foot shapes while maintaining protection. The anatomical, removable PU foam footbed keeps the foot cool and comfortable over extended rides.
The inner (medial) side entry opening system features an elastic-mounted zipper with an extra-wide Velcro flap, providing a precise, secure fit and wide aperture for easy entry and removal. The highly ergonomic last ensures a precise fit tailored to the rider's anatomy, promoting confidence and control on every ride. These features make the Alpinestars SMX-S Boots a versatile and high-performance choice for motorcycle enthusiasts who demand both protection and comfort in their gear.
