Alpinestars SMX-6 v3 Gore-Tex® Boots — EU 44, Black, Gray

Designed for high-performance street riding, these boots pair a lightweight microfiber upper with a waterproof, highly breathable Gore-Tex® liner for reliable all-weather protection.

• Advanced microfiber construction delivers abrasion resistance with excellent flexibility for natural movement.
• Waterproof Gore-Tex® liner ensures breathability and weather protection without sacrificing comfort.
• New front and rear flexion zones feature textile over-injected with soft TPU for enhanced impact abrasion resistance while promoting natural forward and backward motion.
• An evolved ankle-brace protection system provides bio-mechanical support between the lateral top calf, shin and ankle to limit hyper-torsion, hyper-extension and hyper-flexion while protecting the Achilles and ankle.
• Lace-Lock system made from advanced polymer resin guarantees a quick, precise and secure closure.
• Targeted protection includes a TPU shifter zone, race-derived TPU shin plate, and dual-density TPU ankle protectors positioned between the upper and lining for strategic impact resistance.
• Replaceable dual-density toe slider with screw-in assembly, plus replaceable heel and external side heel sliders for optimized shock dissipation and sliding performance.
• Composition: 37% TPU, 35% microfiber, 11% polyester, 8% polyurethane, 8% TPR, 1% elastic. Lining: 99% polyester, 1% microfiber.

Engineered for riders who demand protective performance and walking comfort, these boots balance rigid impact zones with flexible construction to support natural articulation on and off the bike.
