The Alpinestars SMX-6 V3 Motorcycle Boots deliver race-derived protection and performance for track riding and street use. Finished in Black/Silver/Red, this size US 9.5 / EU 44 boot features an advanced microfiber upper that provides lightweight abrasion resistance, flexibility, and dependable support. The SMX-6 V3 is designed for riders who want a high-performance motorcycle boot with protective materials and mobility suited to aggressive riding.
Protection is built into key impact and abrasion zones throughout the boot. Alpinestars’ ankle brace protection system provides biomechanical support between the calf, shin, and ankle while helping limit hyper-torsion, hyper-extension, and hyper-flexion. Dual-density TPU ankle protectors, a race-derived TPU shin plate, and a TPU shifter zone help protect the lower leg, ankle, and medial side of the foot. Front and rear flex zones combine textile construction with soft TPU over-injection to support natural forward and backward movement without sacrificing coverage.
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 impact energy and promote controlled sliding during a crash. The SMX-6 V3 is an excellent fit for sportbike riders, track-day enthusiasts, and street riders seeking a protective boot with race-inspired technology.
