Alpinestars SMX-6 V3 Racing Motorcycle Boots – Black/Silver/Red, US 12 / EU 47, Part #2223025-199-47

The Alpinestars SMX-6 V3 boots are engineered for riders seeking superior protection and performance on both track and street. Featuring an advanced microfiber upper, these boots provide lightweight durability and abrasion resistance while maintaining exceptional flexibility for natural foot movement. The front flex and back flexion zones are reinforced with textile over-injected with soft Thermoplastic Polyurethane (TPU), enhancing impact resistance and allowing smooth forward and backward motion during aggressive riding. The innovative ankle brace system offers biomechanical support, stabilizing the ankle and limiting hyper-torsion, hyper-extension, and hyper-flexion, thereby reducing injury risk while providing excellent ankle articulation. Strategically incorporated, the lace-lock system uses an advanced polymer resin for secure, quick, and precise closure, ensuring a snug fit that stays in place during intense riding sessions. The boots also feature a TPU shifter zone for added protection on the lower medial side, protecting against impacts and abrasion. A race-derived TPU shin plate protector is positioned to deliver superior impact and abrasion resistance, safeguarding critical areas during high-speed riding. Dual density TPU ankle protectors are integrated between the upper and padded lining to enhance key area protection without sacrificing comfort. Additional features include a replaceable dual density TPU toe slider with screw-in assembly for comprehensive outer toe protection, combined with flexibility for walking. The heel slider and external side heel slider are designed for optimal shock absorption and sliding in the event of a fall, providing added safety and durability. Built with high-performance materials and innovative safety features, the Alpinestars SMX-6 V3 boots are the ultimate choice for serious riders demanding both protection and performance in a sleek, race-inspired design.
