The Alpinestars SMX-6 V3 motorcycle boots are designed for riders who demand track-ready protection and reliable street performance. This black, silver, and red model is sized at US 7.5 and EU 41, making it a performance-focused option for riders seeking a secure fit with race-derived technology. The advanced microfiber upper combines lightweight construction, abrasion resistance, and flexibility for confident movement on and off the motorcycle.
Protection is built into every critical area of the boot. 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 helps support the ankle and limit hyper-torsion, hyper-extension, and hyper-flexion while also protecting the Achilles area and ankle from impacts. Dual-density TPU ankle protectors and a race-derived TPU shin plate provide targeted coverage for common impact zones.
Additional performance features include the Alpinestars Lace-Lock System, which uses an advanced polymer resin for fast, precise, and secure closure. A TPU shifter zone protects the lower medial side of the boot, while the replaceable dual-density TPU toe slider, replaceable heel slider, and external side heel slider provide protection, shock dissipation, and controlled sliding during an incident. These components also preserve flexibility for improved walking comfort. The SMX-6 V3 is suitable for sport riding, track days, and aggressive street use where advanced boot protection and mobility are essential.
