The Alpinestars SMX Plus motorcycle boots deliver advanced protection, flexibility, and secure fitment for sport and performance riding. This black, white, and yellow fluorescent model is sized at US 7.5 / EU 41 and features an advanced microfiber upper for lightweight durability and abrasion resistance. Large front and rear accordion zones, a flexible Achilles panel, and a stretchable entry panel support natural forward and backward movement while maintaining a close, comfortable fit.
Designed for protective coverage during demanding rides, the Alpinestars Multi-Link Control system helps limit ankle hyper-torsion, hyper-extension, and hyper-flexion while providing support and impact protection around the ankle and Achilles area. A contoured high-modulus shin plate adds impact and abrasion resistance, while dual-density TPU toe sliders, a replaceable heel slider, and an external side heel slider help protect key contact areas and promote controlled sliding during an accident. The toe and heel sliders are replaceable for continued serviceability.
Fitment is refined through an inner instep speed-lacing closure, Alpinestars Lace-Lock System, micro-adjustable ratchet top closure, and a lateral zipper. Hook-and-loop retention keeps the zipper pull secured and flat. The anatomical replaceable EVA footbed provides arch support and pedal feel, while the durable textured rubber sole supplies consistent grip and riding feedback. Breathable lining in the ankle and leg areas, combined with open-cell foam laminated into the synthetic forefoot lining, helps improve comfort during extended use.
