The Alpinestars SMX-6 V3 motorcycle boots are race-inspired performance riding boots designed for track use and street riding. This black model is sized US 6.5 / EU 40 and features an advanced microfiber upper that delivers lightweight abrasion resistance, flexibility, and dependable protection. Manufacturer part number and vendor part number: 2223025-10-40.
Designed for controlled movement and impact protection, the SMX-6 V3 uses textile flex zones over-injected with soft Thermoplastic Polyurethane (TPU) to support natural forward and backward motion while helping resist abrasion. Alpinestars’ ankle brace protection system provides biomechanical support between the calf, shin, and ankle, helping limit hyper-torsion, hyper-extension, and hyper-flexion while protecting the Achilles tendon and ankle during performance riding.
The Alpinestars Lace-Lock System uses an advanced polymer resin closure for a secure, precise fit. TPU protection is positioned at the shifter area and shin, while dual-density ankle protectors are integrated between the upper and padded lining for targeted coverage. Replaceable dual-density TPU toe sliders, a replaceable heel slider, and an external side heel slider help dissipate impact and encourage controlled sliding in the event of an accident. The SMX-6 V3 fits riders seeking protective motorcycle footwear with race-derived features, walking flexibility, and performance-focused support.
