The Alpinestars SMX-S Boots are designed for riders seeking a combination of comfort, protection, and performance. Crafted with a durable microfiber upper, these boots offer excellent flexibility and a snug fit, ensuring all-day comfort during long rides or intense track sessions. The high-tech micro-fiber construction provides a lightweight yet resilient shell that withstands impacts and abrasions, while the ergonomic forefoot shaping enhances control and precision. An innovative rubber compound sole with structured shank reinforcement delivers optimal support and stability, crucial for aggressive riding styles.
Impact protection is prioritized with double-injected polyurethane (PU) shields on the shin, ankle, calf, toe, and heel. The inner protection panel, seamlessly connected to the heel counter and running along the outer ankle, adds an extra layer of defense against injuries. The quick-drying polyamide lining, laminated with open-cell foam and high-density padding, efficiently absorbs shocks and keeps the foot cool, even during rigorous activity. The large ‘throat’ profile instep and Achilles flex bellows provide superior flex and comfort, accommodating natural foot movement.
Designed for ease of use, the SMX-S features an innovative medial side entry system with an elastic-mounted zipper and an extra-wide Velcro® flap, allowing for a precise fit and effortless on/off. The boots are equipped with strategically placed air vents at the ankle, heel, and forefoot, covered with specialized mesh to promote airflow and rider comfort. The removable PU foam footbed and MTP mesh liner further enhance breathability and support. An interchangeable bi-injected PU toe slider with snap-in assembly offers additional customization and protection.
