The Alpinestars SMX Plus V2 Vented Motorcycle Boots deliver advanced protection, flexible performance, and a secure fit for sport and track riding. This size US 5 / EU 38 boot features a lightweight microfiber upper reinforced with high-performance polymer protectors and Alpinestars’ Multi-Link Control (MLC) system. The MLC design helps limit ankle hyper-torsion, hyper-extension, and hyper-flexion while allowing natural articulation and movement.
Designed for comfort during aggressive riding, the boot uses flexible microfiber front and Achilles accordion zones, asymmetrical flex panels, and stretch accordion construction at the entry area. Ventilated heel and shin TPU sections promote airflow, while the breathable ankle and leg lining and open-cell foam forefoot lining help manage comfort and impact absorption. The anatomical, replaceable EVA footbed provides arch support and improved pedal feel.
Protection features include a contoured high-modulus shin plate, wide heel counter, self-molding ankle protectors, and impact-absorbing heel inserts. Replaceable dual-density toe sliders and heel sliders help protect key contact areas and encourage controlled sliding during an incident. The durable rubber sole provides consistent grip and riding feel. An inner instep speed-lacing closure, Alpinestars Lace-Lock System, micro-adjustable ratchet top closure, and lateral zipper create a precise, secure fit. The included hook-and-loop tab keeps the zipper pull secured and flat. Manufactured by Alpinestars, this boot is identified by manufacturer and vendor part number 2221119-1231-38.
