Alpinestars SMX-6 V3 Boots Black/Silver/Red US 6.5 - Part Number 2223025-199-40

The Alpinestars SMX-6 V3 Boots are engineered for high-performance racing and street riding, offering advanced protection and innovative features for optimal safety and comfort. Constructed with an advanced microfiber upper, these boots provide lightweight durability, exceptional abrasion resistance, and enhanced flexibility, ensuring riders can move freely while maintaining high levels of protection. The front and back flex zones are reinforced with textile over-injected thermoplastic polyurethane (TPU), promoting natural foot movement and providing impact resistance during aggressive riding scenarios. The bio-mechanical ankle brace support system stabilizes the ankle by supporting the lateral top calf, shin, and ankle, while limiting hyper-torsion, hyper-extension, and hyper-flexion, thereby reducing injury risk and improving ankle articulation. Alpinestars’ Lace-Lock System features an advanced polymer resin construction, ensuring quick, precise, and secure closure for a reliable fit and quick adjustments during races or rides. A TPU shifter zone on the lower medial side offers superior protection against impacts and abrasion, essential for aggressive shifting and track conditions. For impact absorption and abrasion resistance, the boots feature a race-derived TPU shin plate protector and dual-density TPU ankle protectors, strategically positioned to safeguard key areas without sacrificing mobility. The replaceable dual-density TPU toe slider with screw-in assembly offers comprehensive outer toe protection, combining durability with walking comfort. Additional impact mitigation is achieved through replaceable heel sliders and external side heel sliders, which are designed for shock absorption and facilitate sliding in the event of a fall, minimizing injury risk. Overall, the Alpinestars SMX-6 V3 Boots combine race-derived technology and protective features to deliver a comprehensive riding experience, whether on the track or street, ensuring safety without compromising performance or comfort.
