The Alpinestars SMX Plus Motorcycle Boots are high-performance riding boots designed for sport and track-focused motorcyclists who demand advanced protection, precise fit, and flexible movement. This black, white, and yellow fluorescent model is sized for US 8 / EU 42 and features an advanced microfiber upper that helps reduce weight while delivering excellent abrasion resistance and flexibility. The Alpinestars SMX Plus boots are built for riders seeking dependable protection during aggressive street riding, track days, and performance-oriented motorcycle use.
Protection is provided by Alpinestars Multi-Link Control system, which supports ankle articulation while limiting hyper-torsion, hyper-extension, and hyper-flexion. A contoured high-modulus shin plate, Achilles protection, and ankle impact protection help shield key areas during a crash. Dual-density TPU replaceable toe sliders, a replaceable heel slider, and an external side heel slider are positioned to help absorb and dissipate impact while promoting controlled sliding. Flexible accordion microfiber zones at the front, rear, and Achilles improve natural forward and backward movement without compromising coverage.
The Alpinestars SMX Plus uses a secure inner instep speed-lacing closure, lateral zipper, and Alpinestars Lace-Lock System for a precise, adjustable fit. A micro-adjustable ratchet top closure provides additional security, while the hook-and-loop tab keeps the zipper pull flat and protected. The anatomical replaceable EVA footbed supports the arch and helps maintain pedal feel. A breathable, padded lining enhances comfort, and the durable rubber sole provides consistent grip and improved riding feedback. The manufacturer is Alpinestars, and the vendor part number is 2221019-125-42.
