Alpinestars SMX Plus Motorcycle Boots - Black, White & Yellow Fluorescent US 6.5 / EU 40 (Part #2221019-125-40)

The Alpinestars SMX Plus boots are crafted with an advanced microfiber upper that offers lightweight protection combined with high flexibility, making them ideal for aggressive riding styles. The front flex zone, constructed from soft microfiber, enhances abrasion resistance while allowing natural forward and backward foot movement. Additionally, the flexible accordion microfiber on the Achilles area provides improved natural motion and comfort during extended rides. The outside entry and exit feature a stretchable accordion panel that ensures a snug fit and easy removal, reducing rider fatigue.
The boots incorporate an evolution of Alpinestars' unique Multi-Link Control system, delivering external protection and support for ankle articulation. This system limits hyper-torsion, hyper-extension, and hyper-flexion, while also safeguarding the Achilles and ankle areas from impacts. The design includes a replaceable dual-density Thermoplastic Polyurethane (TPU) toe slider with a screw-in assembly for customizable protection around the outer toe, along with replaceable heel sliders positioned to dissipate shocks and facilitate sliding during falls. Large asymmetrical accordion zones at the front and rear optimize flexibility, ensuring maximum comfort and safety.
A micro-adjustable ratchet top closure with a stowable tab end provides a secure fit, while the advanced synthetic forefoot lining laminated with open-cell foam offers excellent shock absorption. The highly breathable lining in the ankle and leg areas enhances overall comfort during rides. The anatomically designed and replaceable EVA footbed supplies arch support and a responsive pedal feel. The sole features an evenly textured rubber surface for consistent grip, designed to improve rider feedback and control.
The inner instep speed lacing closure combined with a lateral zipper ensures a precise and secure fit. The innovative Lace-Lock System, made from advanced polymer resin, allows for quick, secure tightening, while a hook-and-loop tab locks the zipper pull in place for added safety. The contoured high-modulus shin plate protector delivers superior impact resistance and abrasion protection, completing this high-performance motorcycle boot designed for both safety and comfort.
