Alpinestars SMX-6 V3 Motorcycle Boots - Black, Silver & Red, US 9.5 / EU 44

The Alpinestars SMX-6 V3 boots are engineered for riders seeking high-performance protection and comfort on both track and street. Featuring an advanced microfiber upper construction, these boots offer lightweight durability, abrasion resistance, and excellent flexibility for dynamic riding movements. Strategically designed with front and back flex zones, the boots incorporate textile over-injected with soft thermoplastic polyurethane (TPU) to enhance impact abrasion resistance while maintaining natural movement and agility during riding.
Equipped with Alpinestars' innovative ankle brace protection system, the SMX-6 V3 provides superior biomechanical support between the lateral calf, shin, and ankle. This system limits hyper-torsion, hyper-extension, and hyper-flexion, helping prevent injuries while offering optimal ankle articulation. The boots also feature a quick and secure Lace-Lock System made from advanced polymer resin, ensuring a precise fit with minimal effort, and a TPU shifter zone that delivers superior protection on the lower medial side, ideal for aggressive riding styles.
The protective features extend to race-derived TPU shin plate protectors, dual density TPU ankle guards, and replaceable components such as the TPU toe slider, heel slider, and external side heel slider. These elements are designed for maximum impact and abrasion resistance, shock absorption, and ease of replacement after impacts. The strategically placed sliders promote sliding in the event of a fall, providing essential protection and reducing injury risk. Overall, the Alpinestars SMX-6 V3 boots combine advanced materials, innovative protection systems, and thoughtful design to deliver a high-performance riding experience with enhanced safety and comfort.
