The Alpinestars SMX-6 V3 Motorcycle Boots are performance-focused riding boots designed for track days, sport riding, and street use. This black model is sized US 12.5 / EU 48 and features a race-derived construction that balances protection, flexibility, and rider control. The advanced microfiber upper provides lightweight abrasion resistance while maintaining the mobility needed for aggressive riding positions and everyday walking.
Protection is built into the boot through Alpinestars' unique ankle brace system, which supports the connection between the lower calf, shin, and ankle while helping limit hyper-torsion, hyper-extension, and hyper-flexion. Dual-density TPU ankle protectors, a race-derived TPU shin plate, and integrated Achilles and ankle impact protection help shield key areas during a crash. Front and rear flex zones use textile over-injected with soft TPU to improve impact and abrasion resistance without restricting natural forward and backward movement.
The SMX-6 V3 includes Alpinestars' Lace-Lock System, made from advanced polymer resin for fast, precise, and secure closure. A TPU shifter zone protects the lower medial side of the boot, while replaceable dual-density TPU toe sliders, a replaceable heel slider, and an external side heel slider provide additional coverage and support controlled sliding during an incident. These features also help preserve walking flexibility between riding sessions.
