The Alpinestars SMX Plus boots are engineered for high-performance motorcycle riding, combining advanced materials and innovative design features to ensure optimal safety, comfort, and flexibility. Constructed with an advanced microfiber upper, these boots offer lightweight protection with enhanced abrasion resistance and natural movement enabling riders to maintain agility on the road. The front flex zone, made from soft microfiber, allows for improved forward and backward mobility, while the flexible accordion microfiber on the Achilles provides additional natural movement and comfort during extended rides.
The outside entry and exit are facilitated by a stretchable accordion panel that ensures a close fit and effortless donning and removal. An evolution of Alpinestars’ unique Multi-Link Control system provides external protection and support for ankle articulation, effectively limiting hyper-torsion, hyper-extension, and hyper-flexion. This system also offers impact protection for the Achilles and ankle areas, enhancing rider safety. The boots feature a dual-density TPU (Thermoplastic Polyurethane) replaceable toe slider with a screw-in assembly, offering durable coverage around the outer toe, while the replaceable heel and side sliders are positioned to absorb shocks and promote sliding in case of a fall, reducing injury risk.
Large, asymmetrical accordion zones at the front and rear are designed to maximize flexibility and comfort, allowing for unrestricted movement and enhanced safety. The micro-adjustable ratchet closure system ensures a secure fit and easy adjustment, with a stow tab for convenience. The advanced synthetic forefoot lining, laminated with open-cell foam, provides shock absorption, while the breathable lining in the ankle and leg areas enhances overall comfort during long rides. An anatomically designed, replaceable EVA footbed offers arch support and a precise pedal feel, contributing to rider control and fatigue reduction.
The outsole is durable and textured for consistent grip, improving rider feel and stability. Inner instep speed lacing combined with a lateral zipper allows for a precise and secure fit, while the innovative Lace-Lock System, made from advanced polymer resin, ensures quick, secure closure. A hook-and-loop tab locks the zipper pull in place for added safety. The contoured high-modulus shin plate protector delivers superior impact and abrasion resistance, further safeguarding the rider’s leg. Designed with performance and safety in mind, the Alpinestars SMX Plus boots are an ideal choice for motorcyclists seeking premium gear that combines advanced technology with practical features for everyday riding or competitive use.
