Alpinestars SMX-6 V3 Motorcycle Racing Boots - Black, Silver, and Red, US 10.5 / EU 45

The Alpinestars SMX-6 V3 boots are engineered for riders seeking high-performance protection and advanced technology on both the track and street. Crafted with an innovative microfiber upper, these boots offer lightweight durability, excellent abrasion resistance, and exceptional flexibility for natural movement. The front flex and back flexion zones are reinforced with textile over-injected thermoplastic polyurethane (TPU), providing impact resistance while supporting smooth forward and backward motion. These design features ensure riders maintain agility without compromising safety.
The boots feature Alpinestars' unique ankle brace protection system, which delivers biomechanical support and shields the lateral calf, shin, and ankle. This system limits hyper-torsion, hyper-extension, and hyper-flexion, reducing injury risk during aggressive riding. Additionally, the ankle support enhances articulation for a more natural feel, while also offering superior Achilles and ankle impact protection. The lace-lock system is constructed from advanced polymer resin, allowing for quick, precise, and secure closure, ensuring a snug fit during intense riding sessions.
Strategically placed, race-derived TPU shin plate protectors provide excellent impact and abrasion resistance, safeguarding critical areas from debris and collisions. The dual-density TPU ankle protectors are positioned between the upper and padded lining to deliver targeted protection without sacrificing comfort. The boots also include a replaceable dual-density TPU toe slider with a screw-in assembly for comprehensive coverage around the outer toe, along with flexibility for walking. Shock-absorbing heel sliders and external side heel sliders are designed to dissipate impact energy efficiently and facilitate sliding in the event of a fall, enhancing rider safety and confidence. Overall, the Alpinestars SMX-6 V3 boots combine advanced materials, innovative safety features, and superior comfort to meet the demands of serious motorcyclists.
