The Alpinestars SMX Plus V2 Vented Motorcycle Boots combine sport-focused styling with advanced protection and rider-focused comfort. This black and red model is sized US 9.5 / EU 44 and features a lightweight microfiber upper reinforced with polymer protection. The boots are designed for motorcycle riders seeking secure support, flexibility, ventilation, and dependable coverage during street or track use. Manufacturer and vendor part number 2221119-13-44 identifies this specific Alpinestars configuration.
Protection: Alpinestars Multi-Link Control (MLC) system helps limit ankle hyper-torsion, hyper-extension, and hyper-flexion while preserving natural articulation. The contoured high-modulus shin protector, wide heel counter, shock-absorbing ankle inserts, and reinforced outer construction help protect against impact and abrasion. Dual-density TPU toe sliders, a replaceable heel slider, and an external side heel slider are designed to help dissipate impact and support controlled sliding during an accident.
Comfort and Fit: Soft microfiber flex zones and accordion panels at the front, rear, and Achilles area promote natural movement while improving abrasion resistance. An inner instep speed-lacing closure, lateral zipper, Alpinestars Lace-Lock System, and micro-adjustable ratchet top closure provide a precise, secure fit. The hook-and-loop tab keeps the zipper pull secured and flat when riding.
Ventilation and Ride Feel: Strategically positioned ventilation areas in the heel and shin help promote airflow. The breathable ankle and leg lining, open-cell foam cushioning, anatomical replaceable EVA footbed, and durable textured rubber sole provide comfort, arch support, consistent grip, and improved pedal feel. Replaceable protective sliders and the supportive construction make these boots well suited for riders who want performance-oriented footwear for compatible street and sport motorcycle applications.
