The Alpinestars SMX-6 V3 motorcycle boots deliver race-derived protection and performance for riders who demand dependable coverage on the track and street. Finished in black and sized for US 9 / EU 43, these boots feature an advanced microfiber upper that balances lightweight construction, abrasion resistance, flexibility, and everyday riding comfort. The SMX-6 V3 model is designed to support confident movement while maintaining essential protection in high-impact areas.
Alpinestars’ unique ankle brace protection system provides biomechanical support between the lateral upper calf, shin, and ankle. This system helps control hyper-torsion, hyper-extension, and hyper-flexion while supporting natural ankle articulation and providing Achilles and ankle impact protection. Front and rear flexion zones combine textile construction with soft TPU over-injection to improve impact and abrasion resistance without restricting forward or backward movement.
Additional protection includes a race-derived TPU shin plate, dual-density TPU ankle protectors, a TPU shifter zone, and replaceable dual-density TPU toe and heel sliders. The toe slider uses a secure screw-in assembly, while the heel and external side heel sliders are positioned to promote shock dissipation and controlled sliding during an accident. The Alpinestars Lace-Lock System uses advanced polymer resin for quick, precise, and secure closure.
These boots fit riders seeking a protective sport motorcycle boot for performance riding, track days, and spirited street use. The product is manufactured by Alpinestars and supplied under vendor part number 2223025-10-43.
