The Alpinestars SMX Plus boots are engineered for high-performance motorcycle riding, featuring an advanced microfiber upper construction that offers lightweight durability and exceptional flexibility. The soft microfiber front flex area enhances abrasion resistance while facilitating natural forward and backward movement, allowing riders to maintain comfort during intense riding sessions. Additionally, the flexible accordion microfiber on the Achilles region promotes natural ankle motion, contributing to overall comfort and control. The outside entry and exit are streamlined with stretchable accordion panels, providing a close fit that makes putting on and removing the boots effortless without sacrificing security.
These boots incorporate Alpinestars’ innovative Multi-Link Control system, which offers external protection and support for ankle articulation. This system limits hyper-torsion, hyper-extension, and hyper-flexion movements, reducing the risk of injury while ensuring optimal ankle mobility. Impact protection is further enhanced with a dual-density Thermoplastic Polyurethane (TPU) replaceable toe slider, equipped with a screw-in assembly for easy replacement, safeguarding the outer toe area during aggressive riding or accidental impacts. The heel slider and external side heel slider are designed to absorb shock and promote sliding in the event of a fall, minimizing injury risk.
The large, asymmetrical accordion zones at the front and rear of the boots are strategically positioned to maximize flexibility, ensuring maximum comfort and safety. The micro-adjustable ratchet top closure with a stow tab end allows for a secure and customizable fit. The advanced synthetic forefoot lining laminated with open cell foam offers superior shock absorption, while the highly breathable lining around the ankle and leg enhances overall comfort during extended use. An anatomically designed and replaceable EVA footbed provides arch support and a precise pedal feel, making these boots ideal for serious riders seeking both protection and responsiveness.
The sole is engineered for improved riding feel, with evenly textured rubber that delivers consistent grip on various surfaces. The inner instep speed lacing closure combined with a lateral zipper ensures a secure, snug fit and quick on/off access. The Alpinestars Lace-Lock System, made from an advanced polymer resin, provides a quick, secure closure, while the hook-and-loop tab locks the zipper pull flat for added safety. A contoured high-modulus shin plate protector offers superior impact and abrasion resistance, completing the comprehensive protective features of these high-performance motorcycle boots.
