The Alpinestars SMX-6 V3 motorcycle boots are designed for riders who want race-derived protection, flexibility, and dependable performance on the street or track. This black riding boot is sized US 12 / EU 47 and features an advanced microfiber upper that provides lightweight abrasion resistance while maintaining the flexibility needed for walking and active riding. The manufacturer part number and vendor part number are both 2223025-10-47.
Protective coverage is built into the boot through strategically positioned TPU components, including a shin plate, dual-density ankle protectors, a lower medial shifter zone, and replaceable toe, heel, and external side heel sliders. The Alpinestars ankle brace protection system supports the connection between the calf, shin, and ankle, helping limit excessive twisting, extension, and flexion while supporting natural ankle articulation. The replaceable sliders are designed to help absorb impacts and promote controlled sliding during an accident.
Front and rear flex zones combine textile construction with soft TPU over-injection to improve impact and abrasion resistance without restricting forward-and-back movement. Alpinestars’ Lace-Lock System uses an advanced polymer resin closure for quick, precise, and secure fastening. The SMX-6 V3 is a suitable fit for motorcycle riders seeking performance footwear for sport riding, track days, commuting, and other applications where reinforced ankle, shin, toe, heel, and shift-area protection is required.
