The Alpinestars SMX-6 V3 motorcycle boots are designed for riders who want race-derived protection and performance for both track riding and street use. This black, US 10.5 / EU 45 model combines an advanced microfiber upper with strategically placed TPU protection to provide a strong balance of abrasion resistance, impact protection, flexibility, and riding comfort. The boots are manufactured by Alpinestars and identified by manufacturer and vendor part number 2223025-10-45.
Alpinestars’ ankle brace protection system provides biomechanical support between the lower calf, shin, and ankle while helping limit hyper-torsion, hyper-extension, and hyper-flexion. The system also contributes to Achilles and ankle impact protection. Front and rear flex zones use textile over-injected with soft TPU to support natural foot movement while enhancing protection. A race-derived TPU shin plate, dual-density TPU ankle protectors, and a TPU shift zone protect key areas during aggressive riding.
The SMX-6 V3 features a secure Alpinestars Lace-Lock System made from advanced polymer resin for quick and precise closure. Replaceable dual-density TPU toe sliders provide coverage around the outer toe area while maintaining walking flexibility. Replaceable heel and external side heel sliders are positioned to help dissipate and absorb impact while supporting controlled sliding during an accident. The Alpinestars SMX-6 V3 is a performance-focused choice for riders seeking protective motorcycle footwear with track-inspired features and dependable street-riding versatility.
