Alpinestars SMX-6 v3 Gore-Tex® Boots — EU Size 45, Black/Gray

The SMX-6 v3 Gore-Tex® boots combine lightweight microfiber construction with race-proven protection for all-weather street use.

• Advanced microfiber upper for abrasion resistance and exceptional flexibility.
• Waterproof, breathable Gore-Tex liner for superior performance in wet conditions.
• Front and rear flexion zones with textile over-injection and soft TPU to enhance impact abrasion resistance while allowing natural forward and backward movement.
• An evolved ankle brace system provides bio-mechanical support between the top calf, shin, and ankle to limit hyper-torsion, hyper-extension and hyper-flexion while protecting the Achilles and ankle.
• Lace-lock system constructed from advanced polymer resin for quick, precise and secure closure.

Protection details:

• Race-derived TPU shin plate for high-level impact and abrasion resistance.
• TPU shifter zone on the lower medial side for added protection.
• Dual-density TPU ankle protectors positioned between the upper and lining for targeted impact mitigation.
• Replaceable dual-density toe slider with screw-in assembly for protection and walking flexibility.
• Replaceable heel and external side heel sliders for optimized shock dissipation and sliding behavior during a crash.
