Alpinestars SMX-S Motorcycle Boots - Black/White US 6 / EU 39, Part Number 2223517-12-39

The Alpinestars SMX-S Boots are engineered for riders seeking a combination of comfort, protection, and high performance. Crafted with a durable microfiber upper, these boots provide an optimal fit while maintaining flexibility and breathability. The innovative design incorporates advanced protective features, including double injected Polyurethane (PU) shields on the shin, ankle, calf, toe, and heel, effectively absorbing impacts and minimizing abrasion during aggressive riding conditions. An inner layer of protection connects to the heel counter via a double injected panel, offering additional security without sacrificing mobility. The quick-drying polyamide lining, laminated with open cell foam and contoured padding, enhances shock absorption and keeps the foot dry and comfortable during long rides or intense sessions.

Designed for rider convenience, the SMX-S features an ergonomic forefoot shape and an expansive 'throat' profile that promotes superior flex and comfort. The structured rubber sole with reinforcement supports the arch and provides reliable grip on various surfaces. The interchangeable bi-injected PU toe slider with a snap-in assembly allows for customization and extended durability. Strategic air vents at the ankle, heel, and forefoot are covered with specialized mesh, ensuring optimal airflow and reducing heat buildup. The large Achilles flex bellows and MTP mesh liner further improve flexibility and ventilation, making these boots suitable for demanding riding environments.

Additional features include an innovative side entry system with an elastic-mounted zipper and wide Velcro® flap for a precise, comfortable fit with easy access. The highly ergonomic last ensures an ultra-precise fit, while the removable PU foam footbed offers customizable comfort and enhanced breathability. Whether you're racing or touring, the Alpinestars SMX-S Boots provide the protection, support, and comfort necessary to perform at your best while ensuring rider safety and confidence.
