The Alpinestars SMX-S Boots in Black/White provide riders with a precise fit, dependable protection, and everyday comfort. Designed for motorcycle use, these boots feature a durable microfiber upper that offers flexibility and abrasion resistance while supporting an ergonomic riding position. The SMX-S model uses layered protective components throughout the foot, ankle, shin, calf, toe, and heel for comprehensive coverage without unnecessarily restricting movement.
Protection: Double-injected polyurethane shields help protect the shin, ankle, calf, toe, and heel from impact and abrasion. Inner ankle protection is integrated beneath the outer shell and connected to the heel counter for additional support. A replaceable, bi-injected polyurethane toe slider uses a snap-in assembly for convenient service and performance.
Comfort: A quick-drying polyamide lining, open-cell foam, and contoured high-density padding help absorb shocks while maintaining a comfortable interior. The anatomical, removable polyurethane foam footbed and MTP mesh liner promote a cooler, more comfortable fit. Air vents at the ankle, heel, and forefoot are covered with protective mesh to encourage airflow.
Fit and Closure: The highly ergonomic last is shaped for a precise fit, while the large instep and Achilles flex bellows allow natural movement. An inner-side entry system combines an elastic-mounted zipper with an extra-wide hook-and-loop flap for easy access and secure adjustment. The exclusive rubber compound sole includes structured shank reinforcement to support the arch. These Alpinestars SMX-S boots are sized for US 6.5 / EU 40 and are identified by manufacturer and vendor part number 2223517-12-40.
