The Alpinestars SMX-6 V3 Motorcycle Boots deliver race-derived protection and performance for track riding and street use. Designed in black for riders who demand responsive control and dependable coverage, these boots feature an advanced microfiber upper that combines lightweight construction, abrasion resistance, and flexibility. The US 9.5 / EU 44 fit is identified by manufacturer part number 2223025-10-44 and vendor part number 2223025-10-44.
Protection is integrated throughout the boot with front and rear flexion zones made from textile over-injected with soft Thermoplastic Polyurethane (TPU). This construction helps resist impact and abrasion while supporting natural forward and backward movement. Alpinestars’ ankle brace protection system provides biomechanical support between the upper calf, shin, and ankle, helping limit hyper-torsion, hyper-extension, and hyper-flexion while protecting the Achilles tendon and ankle. Dual-density TPU ankle protectors, a race-derived TPU shin plate, and a TPU shifter zone provide additional coverage in key impact areas.
The Alpinestars Lace-Lock System uses an advanced polymer resin closure for quick, precise, and secure fastening. A replaceable dual-density TPU toe slider with screw-in assembly protects the outer toe area while maintaining walking flexibility. Replaceable heel and external side heel sliders are positioned to help dissipate and absorb shock while encouraging controlled sliding during an accident. Built for performance-oriented riders, the SMX-6 V3 offers protective fitment for compatible motorcycle riding applications on both the road and track.
