The Alpinestars SMX-6 V3 motorcycle boots are designed for riders who need track-focused protection with the flexibility and comfort required for street riding. This black size US 8/EU 42 boot combines race-derived materials with a performance-oriented chassis to provide dependable abrasion, impact, and torsion protection during aggressive riding. The advanced microfiber upper helps reduce weight while delivering excellent flexibility and abrasion resistance.
Alpinestars’ unique ankle brace protection system supports the area between the lateral calf, shin, and ankle. Its biomechanical design helps limit hyper-torsion, hyper-extension, and hyper-flexion while supporting natural ankle articulation. Front and rear flex zones use textile over-injected with soft Thermoplastic Polyurethane (TPU), promoting controlled forward and backward movement without sacrificing protective coverage. A race-derived TPU shin plate, dual-density TPU ankle protectors, and Achilles protection help safeguard key areas during impact.
The Alpinestars Lace-Lock System uses an advanced polymer resin closure for a precise, secure fit. A TPU shifter zone protects the lower medial side of the boot, while replaceable dual-density TPU toe sliders provide coverage around the outer toe area without limiting walking comfort. Replaceable heel and external side heel sliders are positioned to help dissipate impact energy and encourage sliding during an accident. This Alpinestars SMX-6 V3 boot is supplied by the manufacturer under vendor part number 2223025-10-42 and is intended for riders seeking versatile protection for both track and performance street use.
