Alpinestars SMX-6 V3 Boots — EU 39, Black

Engineered for track and high-performance riding, these boots combine advanced safety and protective technologies to give riders a crucial performance edge on both track and street. 🏁

The upper features a lightweight, abrasion-resistant construction that maintains superb flexibility. Front flex and rear flexion zones use textile over-injected with a soft protective polymer to enhance impact abrasion resistance while promoting natural forward and backward movement.

• An integrated ankle brace protection system provides biomechanical support between the lateral top calf, shin and ankle to limit hyper-torsion, hyper-extension and hyper-flexion while offering Achilles and ankle impact protection.
• A secure lace-lock closure constructed from advanced polymer resin delivers a quick, precise and reliable fit.
• A reinforced shifter zone and strategically positioned shin plate provide superior impact and abrasion resistance.
• Dual-density ankle protectors placed between the upper and padded lining protect key areas without compromising comfort.
• Replaceable toe and heel sliders with screw-in assemblies offer comprehensive protective coverage and promote controlled sliding and shock dissipation in the event of an accident.

Composition (approx.): 37% protective polymer, 35% synthetic upper material, 11% woven fiber, 8% coated polymer, 8% rubber-like polymer and 1% elastic. Inner lining: 82% woven fiber and 18% synthetic.
