Alpinestars SMX-6 V3 Boots — EU 41, US 7.5, Mid-Calf

These boots are engineered for track and performance riding, combining race-derived protection with flexibility and comfort. Packed with innovative safety and protective features, they give riders a crucial performance edge on both track and street.

• Advanced upper construction for lightweight abrasion resistance and high levels of flexibility.
• Front flex and rear flexion zones with soft over-injected protection to enhance impact abrasion resistance while promoting natural forward and backward movement.
• A unique ankle brace protection system provides biomechanical support between the upper calf, shin and ankle to improve articulation and limit hyper-torsion, hyper-extension and hyper-flexion while offering Achilles and ankle impact protection.
• A lace-lock closure engineered from advanced polymer for a quick, precise and secure fit.
• Reinforced shifter zone and a race-derived shin plate deliver superior impact and abrasion resistance.
• Dual-density ankle protectors and replaceable toe and heel sliders provide targeted shock dissipation and simple serviceability after wear.

Replaceable sliders use a screw-in assembly for comprehensive protective coverage while maintaining walking comfort. The inner lining is engineered for comfort and breathability during intense riding sessions.
