The Alpinestars SMX Plus Motorcycle Boots combine advanced protection, flexible movement, and secure fitment for sport and performance riding. This black, white, and yellow fluorescent model is offered in US men's size 6.5 / EU 40 and is identified by manufacturer part number 2221019-125-40. The vendor part number is 2221019-125-40. Built with an advanced microfiber upper, the boots provide lightweight durability, abrasion resistance, and the flexibility needed for natural forward and backward movement on the motorcycle.
Protection is supported by Alpinestars' Multi-Link Control system, which helps limit hyper-torsion, hyper-extension, and hyper-flexion while protecting the ankle and Achilles area from impacts. A contoured high-modulus shin plate adds impact and abrasion protection, while dual-density TPU toe sliders, a replaceable heel slider, and an external side heel slider provide coverage and help dissipate energy during an accident. Large asymmetrical accordion zones at the front and rear improve comfort and mobility without compromising the boot's supportive structure.
The SMX Plus features an inner instep speed-lacing closure, a lateral zipper, and the Alpinestars Lace-Lock System for precise, secure adjustment. A micro-adjustable ratchet top closure stows the tab end, and a hook-and-loop tab secures the zipper pull in a flat position. An open-cell foam-lined synthetic forefoot lining and breathable ankle and leg areas support comfort during extended rides. The anatomical, replaceable EVA footbed provides arch support and pedal feel, while the durable rubber sole delivers consistent grip and riding feedback. These boots are designed to fit riders seeking race-inspired protection and dependable performance for compatible motorcycle and sport-riding applications.
