Manufacturer part number and vendor part number: 2223025-1406-46.
Fitment: These boots are designed to fit riders who wear a US men's 11.5 or EU 46 motorcycle boot. The performance-oriented construction supports an aggressive riding position while maintaining flexibility for walking and general off-bike movement. Front and rear flex zones combine textile panels with soft thermoplastic polyurethane (TPU) over-injection to support natural forward and backward movement while helping protect against impact and abrasion.
The Alpinestars ankle brace protection system provides biomechanical support between the calf, shin, and ankle. It helps limit hyper-torsion, hyper-extension, and hyper-flexion while supporting Achilles and ankle impact protection. A secure Alpinestars Lace-Lock System uses an advanced polymer resin closure for quick, precise adjustment. Additional protective elements include a TPU shifter zone, race-derived TPU shin plate, dual-density TPU ankle protectors, and replaceable dual-density TPU toe sliders with screw-in mounting. Replaceable heel and external side heel sliders are positioned to help dissipate impact and encourage controlled sliding during an accident. The Alpinestars SMX-6 V3 combines track-focused protection, rider mobility, and durable construction in a versatile sport riding boot.
