Alpinestars SMX Plus Motorcycle Boots Black/White/Red Fluorescent US 12 / EU 47 — Part 2221019-1231-47

Experience superior protection and flexibility with the Alpinestars SMX Plus motorcycle boots, crafted from advanced microfiber upper construction for lightweight performance. The soft microfiber front flex area enhances abrasion resistance while allowing natural forward and backward movement, reducing rider fatigue during long rides. The flexible accordion microfiber on the Achilles region provides improved natural movement and comfort, supporting dynamic riding postures. An outside stretchable accordion panel ensures a close fit, making entry and removal effortless without compromising stability or safety. The innovative Multi-Link Control system offers enhanced external support for ankle articulation, effectively limiting hyper-torsion, hyper-extension, and hyper-flexion, while also safeguarding the Achilles and ankle from impacts. Dual density Thermoplastic Polyurethane (TPU) replaceable toe sliders, secured with screw-in assemblies, deliver dependable coverage around the outer toe area, protecting against abrasion and impacts. The heel sliders and external side heel sliders are designed to absorb shocks and facilitate sliding during an accident, adding an extra layer of safety. Large front and rear asymmetrical accordion zones are strategically placed to maximize flexibility, ensuring maximum comfort and safety through natural movement. The micro-adjustable ratchet top closure with a stow tab end provides a secure and customizable fit, while the advanced synthetic forefoot lining laminated with open-cell foam offers superior shock absorption. Breathable linings in the ankle and leg areas enhance comfort and moisture management during extended rides. The anatomically designed, replaceable EVA footbed offers arch support and a confident pedal feel, critical for precision riding. The durable rubber sole is engineered for improved grip and consistent feedback, ensuring rider control. Inner instep speed lacing and a lateral zipper deliver precise and secure closure, complemented by the ALPINESTARS Lace-Lock System made from advanced polymer resin for quick, reliable fastening. A hook-and-loop tab locks the zip pull in place for added safety. The contoured high modulus shin plate provides excellent impact and abrasion resistance, completing a comprehensive protective package suitable for aggressive riding styles. These features combine to offer a high-performance, comfortable, and protective motorcycle boot designed for serious riders who demand quality and reliability.
