The Alpinestars SMX Plus motorcycle boots combine advanced protection, precise fit, and flexible performance for sport and street riding. This black, white, and yellow fluorescent model is sized US 10.5 / EU 45 and features an advanced microfiber upper for lightweight durability, abrasion resistance, and natural movement. Large front and rear accordion zones, a soft microfiber flex area, and a flexible Achilles panel support comfortable forward and backward movement while riding.
Protection is provided by Alpinestars’ Multi-Link Control system, which helps limit ankle hyper-torsion, hyper-extension, and hyper-flexion while supporting Achilles and ankle impact protection. A contoured high-modulus shin plate enhances impact and abrasion resistance. Dual-density TPU replaceable toe sliders, a replaceable heel slider, and an external side heel slider provide coverage and help dissipate impact energy during an accident.
The SMX Plus boots use an inner instep speed-lacing closure, lateral zipper, and Alpinestars Lace-Lock System for a secure, adjustable fit. A micro-adjustable ratchet top closure improves upper-leg retention, while the hook-and-loop tab keeps the zipper pull secured. The advanced synthetic lining with open-cell foam supports shock absorption and breathability. An anatomical, replaceable EVA footbed provides arch support and pedal feel, while the durable textured rubber sole delivers consistent grip and riding feedback.
