Alpinestars SMX-6 V3 Boots — EU 44, Mid-calf fit, Black

High-performance track and street riding boot packed with innovative safety and protective features.

The upper uses advanced synthetic constructions for lightweight abrasion resistance and excellent flexibility. Front and rear flexion zones are built with textile over-injected with a soft protective polymer to enhance impact abrasion resistance while promoting natural forward and backward movement.

• Biomechanical ankle brace system provides support between the lateral top calf, shin and ankle, limiting hyper-torsion, hyper-extension and hyper-flexion while protecting the Achilles and ankle.
• A lace-lock system made from advanced polymer resin delivers a quick, precise and secure closure.
• Reinforced shifter zone protects the lower medial side; a race-derived shin plate and dual-density ankle protectors offer superior impact and abrasion resistance.
• Replaceable dual-density toe slider with screw-in assembly, plus replaceable heel and external side sliders, provide shock dissipation and sliding protection while maintaining walking comfort.
• Constructed from engineered polymers, technical synthetics and performance textiles for durability and rider comfort.

Designed for riders who want race-derived protection without sacrificing everyday usability; replaceable components and ergonomic design deliver a performance edge on track and street.
