The Alpinestars SMX Plus V2 Vented Motorcycle Boots combine streamlined sport styling with advanced protection developed by the Alpinestars performance footwear department. This black, white, and yellow pair is sized US 6.5 / EU 40 and features a lightweight microfiber upper reinforced with polymer protection for flexibility, abrasion resistance, and dependable support during aggressive street or track riding. The SMX Plus V2 is designed to provide a secure, performance-oriented fit while maintaining natural movement on and off the motorcycle.
Protection is built around Alpinestars’ Multi-Link Control (MLC) system, which helps limit ankle hyper-torsion, hyper-extension, and hyper-flexion while preserving controlled articulation. A contoured high-modulus shin plate, wide heel counter, molded ankle protectors, shock-absorbing inserts, and replaceable toe and heel sliders provide coverage in key impact areas. Ventilation zones in the heel and shin help promote airflow, while accordion microfiber panels at the front, rear, and Achilles support comfortable forward, backward, and flexing movement.
The Alpinestars SMX Plus V2 includes an inner instep speed-lacing closure, lateral zipper, micro-adjustable ratchet top closure, and Alpinestars Lace-Lock System for a precise and secure fit. An anatomical replaceable EVA footbed supports the arch and enhances pedal feel, while the durable rubber sole provides consistent grip through its textured surface. The advanced synthetic lining and open-cell foam padding help improve comfort and shock absorption. Part number 2221119-125-40 identifies this specific US 6.5 / EU 40 boot configuration.
