Alpinestars SMX-S Motorcycle Boots - Black, US 6 / EU 39, Part Number 2223517-1100-39

The Alpinestars SMX-S Boots are engineered for riders seeking a combination of comfort, protection, and performance. Constructed with a durable microfiber upper, these boots deliver a high level of flexibility and a snug fit. The sophisticated design incorporates advanced protective features such as double injected polyurethane shields on the shin, ankle, calf, toe, and heel to minimize impact and abrasion during demanding rides. An inner protection panel connected to the heel counter provides additional shock absorption and structural integrity to enhance rider safety.
Breathability and comfort are prioritized with a quick-drying polyamide lining laminated with open cell foam and high-density contoured padding. This setup effectively absorbs shocks and maintains foot comfort during extended periods of riding. The exclusive rubber sole features a structured shank reinforcement to support the arch and improve stability. The sole's design includes an interchangeable bi-injected PU toe slider with a snap-in assembly, offering both protection and customization options.
Innovative air vents strategically placed at the ankle, heel, and forefoot are covered with specially designed mesh to promote airflow, keeping feet cool and reducing fatigue. The large ‘throat’ profile, combined with Achilles flex bellows, provides superior flex and a comfortable fit. The MTP mesh liner and removable PU foam footbed further enhance breathability and comfort, making these boots suitable for long rides.
For ease of use, the inner medial side entry system features an elastic-mounted zipper with an extra-wide Velcro® flap, allowing for a precise fit and wide opening for quick, hassle-free access. The highly ergonomic last ensures a precise fit, reducing fatigue and enhancing control. Whether for racing or street riding, the Alpinestars SMX-S Boots offer a comprehensive protective solution with a focus on rider comfort and durability.
