The Alpinestars SMX Plus motorcycle boots are designed for riders who want advanced protection, flexibility, and a secure performance fit. This black model is sized for US 7.5 / EU 41 and features an advanced microfiber upper that helps reduce weight while providing excellent abrasion resistance. The front flex area uses soft microfiber to support natural forward and backward movement, while flexible accordion panels at the Achilles and outer entry area improve comfort, mobility, and ease of entry.
Protection is provided by Alpinestars’ Multi-Link Control system, which supports ankle articulation while helping limit hyper-torsion, hyper-extension, and hyper-flexion. The system also helps protect the Achilles and ankle from impact. A contoured high-modulus shin plate provides additional impact and abrasion resistance. Dual-density TPU replaceable toe sliders, a replaceable heel slider, and an external side heel slider help protect key contact areas, dissipate impact, and promote sliding during an accident.
The SMX Plus boots use large asymmetrical accordion zones to maximize flexibility, along with a micro-adjustable ratchet top closure for a precise fit. An inner instep speed-lacing closure and lateral zipper provide secure adjustment, while the Alpinestars Lace-Lock System uses a polymer resin closure for quick and reliable fastening. The zip pull is secured with a hook-and-loop tab. Inside, breathable ankle and leg linings, open-cell foam padding, and an anatomical replaceable EVA footbed provide comfort, arch support, and pedal feel. The durable rubber sole offers consistent grip for street and track riding.
