Alpinestars SMX-S Motorcycle Boots - Black, US 9 / EU 43 - Part 2223517-1100-43

Designed for rider comfort and maximum protection, the Alpinestars SMX-S Boots feature a durable microfiber upper that offers flexibility and long-lasting wear. The high-tech micro-fiber construction ensures a secure fit while maintaining a lightweight profile, making these boots ideal for both casual and aggressive riding styles. Advanced protective features include double injected polyurethane shields on the shin, ankle, calf, toe, and heel, which provide impact absorption and abrasion resistance. A double injected panel connects to the heel counter, offering added inner protection and structural integrity.
Breathability and comfort are prioritized with the quick-drying polyamide lining laminated with open cell foam and contoured padding, which absorbs shocks and keeps your foot cool during extended rides. The exclusive rubber compound sole with structured shank reinforcement enhances support, especially around the arch, ensuring stability and confidence on the bike. An interchangeable bi-injected PU toe slider with a snap-in assembly adds customization and additional protection for aggressive riding conditions.
Innovative air vents located at the ankle, heel, and forefoot are covered with a specially designed mesh that promotes airflow, reducing heat buildup and enhancing rider comfort. The large ‘throat’ profile, along with Achilles flex bellows, contributes to superior flex and ease of movement. The anatomical, removable PU foam footbed and MTP mesh liner further optimize comfort and breathability. The inner side entry system features an elastic-mounted zipper and an extra-wide Velcro® flap, providing a precise, secure fit with easy access. The highly ergonomic last ensures an ultra-precise fit, making the Alpinestars SMX-S Boots an excellent choice for riders seeking premium protection, comfort, and performance.
The combination of advanced materials, innovative design, and thoughtful features make these boots a versatile and reliable option for motorcycle enthusiasts who demand high-quality gear for their rides.
