The Alpinestars SMX Plus motorcycle boots deliver lightweight, high-performance protection for sport and track riders. This size US 8 / EU 42 model features an advanced microfiber upper for flexibility, abrasion resistance, and dependable support during aggressive riding. Large front and rear accordion zones, a soft microfiber front flex area, and flexible Achilles panels promote natural forward and backward movement while maintaining a close, secure fit.
An evolution of Alpinestars’ Multi-Link Control system provides external ankle protection and support while helping limit hyper-torsion, hyper-extension, and hyper-flexion. The contoured high-modulus shin plate improves impact and abrasion resistance, while replaceable toe, heel, and external side heel sliders help absorb and dissipate impact during an accident. The dual-density TPU toe slider uses a screw-in assembly for convenient replacement and protective coverage around the outer toe area.
The SMX Plus boots use an inner instep speed-lacing closure, Alpinestars Lace-Lock System, and a lateral zipper for a precise, secure fit. The micro-adjustable ratchet top closure stows the tab end, while the hook-and-loop zipper tab keeps the pull flat and secure. An advanced synthetic forefoot lining with open-cell foam provides shock absorption, and breathable ankle and leg lining supports comfort during extended use. The anatomical, replaceable contoured EVA footbed provides arch support and responsive pedal feel. A durable textured rubber sole delivers consistent grip and improved riding feedback.
Manufactured by Alpinestars and supplied under vendor part number 2221019-1231-42, these black, white, and red fluorescent SMX Plus boots are designed to fit riders seeking integrated sport motorcycle protection, mobility, and secure closure performance.
