The Alpinestars SMX-6 V3 motorcycle boots are designed for riders who demand race-derived protection and performance on the track or street. Finished in Black/Silver/Red, this size US 10.5, EU 45 boot uses an advanced microfiber upper for lightweight abrasion resistance, flexibility, and dependable support during aggressive riding.
Front and rear flexion zones combine textile construction with soft Thermoplastic Polyurethane (TPU) over-injection to improve impact and abrasion protection while allowing natural forward and backward movement. Alpinestars’ ankle brace protection system supports the area between the upper calf, shin, and ankle, helping limit hyper-torsion, hyper-extension, and hyper-flexion while providing Achilles and ankle impact protection. The Alpinestars Lace-Lock System uses advanced polymer resin for quick, precise, and secure closure.
Protection continues with a TPU shifter zone, race-derived TPU shin plate, and dual-density TPU ankle protectors positioned between the upper and padded lining. Replaceable dual-density TPU toe sliders provide coverage around the outer toe while maintaining walking flexibility. Replaceable heel and external side heel sliders help dissipate impact energy and encourage controlled sliding during an accident. The Alpinestars SMX-6 V3 is a performance-focused boot for motorcycle riders seeking durable protection, secure fit, and responsive movement.
