The Alpinestars SMX Plus Boots in black offer advanced protection and high-performance features designed for serious motorcyclists. Constructed with an advanced microfiber upper, these boots provide lightweight durability combined with superb flexibility, enabling natural movement and enhancing rider comfort during long rides. The front flex zone, made from soft microfiber, improves abrasion resistance while supporting effortless forward and backward leg motion. An articulated accordion microfiber on the Achilles region grants additional natural movement, reducing fatigue and increasing control. The outside entry and exit are facilitated by a stretchable accordion panel, ensuring a snug fit that allows quick donning and removal. The innovative Multi-Link Control system, an evolution of Alpinestars’ proprietary design, offers superior external protection and support for the ankle, limiting hyper-torsion, hyper-extension, and hyper-flexion movements, while also safeguarding the Achilles and ankle from impact injuries. Dual-density TPU (thermoplastic polyurethane) replaceable toe sliders with screw-in assembly provide robust coverage around the toe area, protecting against abrasions and impacts. The boots also feature replaceable heel sliders and external side heel sliders, positioned to absorb shock and assist sliding in the event of a fall, enhancing safety. Large, asymmetrical accordion zones at the front and rear maximize flexibility, ensuring comfort without compromising safety. The micro-adjustable ratchet top closure with a stowable tab end offers a secure and customizable fit, while the advanced synthetic forefoot lining laminated with open-cell foam provides shock absorption. The high breathability of the ankle and leg linings keeps the rider comfortable in various conditions. An anatomical, replaceable EVA footbed supplies arch support and a precise pedal feel, contributing to better control and comfort. The durable rubber sole, textured for consistent grip, enhances riding feel and safety. Inner instep speed lacing closure combined with a lateral zipper ensures a precise, secure fit, and the Alpinestars Lace-Lock System, made from advanced polymer resin, allows quick and reliable closure. A hook-and-loop tab locks the zipper pull flat and secure. The contoured high-modulus shin plate offers superior impact and abrasion resistance, completing the comprehensive protection features of these high-performance boots.
