SMX Plus Boots - Black/White/Yellow Fluorescent - US 9 / EU 43

The Alpinestars SMX Plus Boots are engineered for riders seeking lightweight, high-performance motorcycle footwear that combines protection with maximum flexibility. Constructed with an advanced microfiber upper, these boots provide a durable yet lightweight barrier against abrasions while allowing natural movement during rides. The front flex zone, made from soft microfiber, enhances abrasion resistance and facilitates smooth forward and backward motion, ensuring comfort without sacrificing safety. An articulated accordion microfiber panel on the Achilles area offers enhanced natural movement and flexibility, supporting a secure fit and improved comfort during extended use. The outside entry/exit features a stretchable accordion panel that conforms closely to the foot and ankle, making donning and removal effortless. The innovative Multi-Link Control system offers superior external ankle support and articulation, limiting hyper-torsion, hyper-extension, and hyper-flexion, while providing impact protection for the Achilles and ankle areas. Dual-density Thermoplastic Polyurethane (TPU) replaceable toe sliders with screw-in assemblies offer reliable protection around the outer toe, and the replaceable heel sliders are strategically positioned to absorb shocks and facilitate sliding in the event of a fall. Large asymmetrical accordion zones at the front and rear maximize flexibility and comfort, ensuring that riders maintain optimal control and safety. The boots feature a micro-adjustable ratchet top closure with a stow tab end for a secure fit, complemented by an advanced synthetic forefoot lining laminated with open-cell foam to absorb shocks. Breathable lining materials in the ankle and leg areas enhance overall comfort, even during extended rides. The anatomically designed and replaceable EVA footbed provides excellent arch support and a responsive pedal feel. The sole is made from durable, textured rubber designed to offer consistent grip on various surfaces, enhancing rider confidence. An inner instep speed lacing closure, combined with a lateral zipper, provides a precise and secure fit, while the Alpinestars Lace-Lock System made from advanced polymer resin ensures quick, secure closures. A hook-and-loop tab locks the zipper pull in place for added safety. The high-modulus contoured shin plate offers superior impact and abrasion resistance, completing the comprehensive protective features of this high-performance motorcycle boot.
