Alpinestars SMX-6 V3 Boots — EU 44, Black/White

Engineered for track and high-performance street riding, the SMX-6 V3 boots blend race-derived technology with practical features for everyday use.

The design focuses on protection, flexibility and comfort with a lightweight microfiber upper that resists abrasion while allowing natural movement. Front flex and rear flexion zones use textile over-injected with soft thermoplastic polyurethane (TPU) to improve impact abrasion resistance and promote natural forward and backward articulation.

• Unique 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 offering Achilles and ankle impact protection.
• Lace-lock system constructed from advanced polymer resin for quick, precise and secure closure.
• TPU shifter zone and strategically positioned TPU shin plate for superior medial and frontal impact and abrasion resistance.
• Dual-density TPU ankle protectors between the upper and padded lining to protect key impact areas.
• Replaceable, dual-density TPU 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. Inner lining: 82% polyester, 18% synthetic.
