The Alpinestars Stella SMX-6 V3 motorcycle boots are anatomically engineered for a women’s specific fit, delivering comfort, flexibility, and race-derived protection for track and performance street riding. This black and white model is sized for US 11 / EU 43 and features an advanced microfiber upper that provides lightweight abrasion resistance while maintaining the flexibility needed for active riding.
Integrated protection is designed to support the foot, ankle, shin, and lower leg during demanding riding conditions. Alpinestars’ unique ankle brace protection system provides biomechanical support between the lateral top calf, shin, and ankle while helping limit hyper-torsion, hyper-extension, and hyper-flexion. Dual-density TPU ankle protectors, a race-derived TPU shin plate, Achilles protection, and a TPU shifter zone provide coverage in key impact and abrasion areas.
The Stella SMX-6 V3 also incorporates front and rear flexion zones made with textile over-injected with soft TPU to encourage natural movement while adding protective reinforcement. The Alpinestars Lace-Lock System uses advanced polymer resin for quick, precise, and secure closure. Replaceable dual-density TPU toe sliders, a replaceable heel slider, and an external side heel slider help dissipate impact energy and promote controlled sliding during an accident. The boots are manufactured by Alpinestars and identified by manufacturer and vendor part number 2223125-12-43. Fitment is intended for women riders seeking a dedicated fit for motorcycle track days, sport riding, and performance-focused street use.
