The Alpinestars SMX-S Boots in Black/White are designed for riders who want a precise fit, dependable protection, and comfortable performance on the road. This size US 5 / EU 38 boot uses a durable high-tech microfiber upper that provides flexibility while helping resist abrasion. The ergonomic last supports a close, performance-oriented fit, while the broad instep and Achilles flex bellows promote natural movement when walking or riding.
Protection is built into the SMX-S design with double-injected polyurethane shields covering the shin, ankle, calf, toe, and heel. An additional inner protection panel is connected to the heel counter and positioned beneath the outer shell along the outer ankle for added coverage. The interchangeable bi-injected polyurethane toe slider uses a snap-in assembly for convenient replacement. A structured shank reinforcement in the exclusive Alpinestars rubber compound sole supports the arch and helps provide reliable traction.
Comfort-focused features include a quick-drying polyamide lining laminated with open-cell foam and high-density contoured padding to help absorb impacts around the foot. Air vents at the ankle, heel, and forefoot are protected by mesh to encourage airflow, while the MTP mesh liner and anatomical removable polyurethane foam footbed help keep the foot comfortable during extended use. The medial-side entry system combines an elastic-mounted zipper with an extra-wide hook-and-loop flap for easy access and a secure, adjustable closure.
