Fitment: These boots are designed to fit riders requiring a US 11.5 or European 46 motorcycle boot size. The SMX-6 V3 is suitable for sportbike, track-day, racing, and performance street riding applications. Its flexible construction supports natural forward and backward movement while maintaining protective coverage around the foot, ankle, shin, heel, and toe.
Protection: An advanced microfiber upper provides lightweight abrasion resistance and flexibility. Textile-over-injected TPU front and rear flex zones enhance impact and abrasion protection while supporting comfortable movement. Alpinestars’ ankle brace system helps limit hyper-torsion, hyper-extension, and hyper-flexion while supporting ankle articulation and protecting the Achilles area. Dual-density TPU ankle protectors, a race-derived TPU shin plate, and a reinforced TPU shifter zone provide additional coverage in key impact areas.

A replaceable dual-density TPU toe slider, replaceable heel slider, and external side heel slider help dissipate impact energy and promote controlled sliding during an accident. The design maintains flexibility for walking comfort, making the Alpinestars SMX-6 V3 a practical choice for riders seeking dependable protection both on the track and on the street.
