The Alpinestars SMX-6 V3 motorcycle boots deliver race-derived protection and performance for track riders and street motorcyclists. Designed in the Black/White/Red Graphic colorway, this size US 12.5 / EU 48 boot features an advanced microfiber upper that helps provide lightweight abrasion resistance, flexibility, and dependable support during aggressive riding. The SMX-6 V3 is built for riders who need responsive protection without sacrificing walking comfort.
Alpinestars’ integrated ankle brace system provides biomechanical support between the calf, shin, and ankle while helping limit hyper-torsion, hyper-extension, and hyper-flexion. Strategically positioned dual-density TPU ankle protectors, a race-derived TPU shin plate, and a TPU shifter zone reinforce key impact and abrasion areas. Front and rear flex zones combine textile construction with soft TPU over-injection to encourage natural movement while maintaining protective coverage.
The Alpinestars Lace-Lock System uses an advanced polymer resin closure for a precise, secure fit. Replaceable dual-density TPU toe sliders use a screw-in assembly for protective coverage around the outer toe, while replaceable heel and external side heel sliders are positioned to help dissipate impact and promote controlled sliding during an accident. The SMX-6 V3 is suitable for motorcycle track and street applications where high-performance protection, secure fitment, and flexible movement are required. This product is manufactured by Alpinestars and supplied under vendor part number 2223025-1406-48.
