Alpinestars SMX-6 V3 Boots — US 12, EU 47, Black

SMX-6 V3 Boots

Packed with race-derived technology, the SMX-6 V3 is a track-focused yet street-capable performance boot that blends protection, flexibility and comfort. Designed to deliver a performance edge, it features advanced materials and dedicated protective systems for demanding riding conditions.

Key construction highlights include an advanced microfiber upper for lightweight abrasion resistance, textile flex zones over-injected with soft TPU for controlled forward and backward movement, and a dedicated TPU shifter zone and shin plate for superior impact protection.

The unique ankle brace system provides biomechanical support across the lateral calf, shin and ankle to limit hyper-torsion, hyper-extension and hyper-flexion while offering Achilles and ankle impact protection. Dual-density TPU ankle protectors, replaceable toe and heel sliders, and external side heel sliders deliver targeted shock dissipation and abrasion resistance without sacrificing walkability.

Materials: microfiber and multi-density TPU components combine with textile linings to balance protection, weight and comfort for both track sessions and street use.
