The Alpinestars SMX-6 V3 motorcycle boots are designed for riders who demand race-derived protection and responsive performance on both the track and street. This black, silver, and red model is sized at US 8 / EU 42 and features an advanced microfiber upper that provides lightweight abrasion resistance, flexibility, and dependable support during aggressive riding.
Protection is built into every critical area. Front and rear flex zones use textile over-injected with soft Thermoplastic Polyurethane (TPU) to help resist impact and abrasion while supporting natural forward and backward movement. Alpinestars’ unique ankle brace protection system delivers biomechanical support between the calf, shin, and ankle, helping limit hyper-torsion, hyper-extension, and hyper-flexion while providing Achilles and ankle impact protection. Strategically positioned dual-density TPU ankle protectors and a race-derived TPU shin plate reinforce key impact zones.
The Alpinestars Lace-Lock System uses advanced polymer resin for quick, precise, and secure closure. A TPU shifter zone protects the lower medial side, while replaceable dual-density TPU toe and heel sliders help dissipate impact and promote controlled sliding during an accident. The external side heel slider adds further protection without compromising walking flexibility. The Alpinestars SMX-6 V3 is a performance-focused boot for riders seeking a secure fit, durable construction, and advanced protection in a versatile street and track design.
