The Alpinestars SMX Plus motorcycle boots are designed for riders who want advanced protection, precise fit, and dependable control on the street or track. This black model is sized for US 6.5 / EU 40 and features an advanced microfiber upper that combines lightweight performance with flexibility and abrasion resistance. The front flex area and accordion microfiber panels at the Achilles and outer entry provide natural forward and backward movement while maintaining a close, supportive fit.
Protection is provided by Alpinestars’ evolved Multi-Link Control system, which supports ankle articulation while helping limit hyper-torsion, hyper-extension, and hyper-flexion. A contoured high-modulus shin plate helps defend against impact and abrasion, while the dual-density TPU replaceable toe slider, replaceable heel slider, and external side heel slider provide coverage and help dissipate impact during an accident. Large asymmetrical accordion zones improve flexibility for comfort and controlled movement while riding.
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 stows the tab end, while a hook-and-loop tab keeps the zipper pull flat and secure. The advanced synthetic forefoot lining uses open-cell foam for shock absorption, with breathable lining through the ankle and leg areas. An anatomical replaceable EVA footbed provides arch support and pedal feel, while the durable rubber sole delivers consistent grip and riding feedback.
