Alpinestars SMX Plus Motorcycle Boots - Black, White & Yellow Fluorescent, US 11.5 / EU 46 (Part #2221019-125-46)

The Alpinestars SMX Plus boots are engineered to provide high-performance protection with a focus on comfort and flexibility for serious riders. Featuring an advanced microfiber upper construction, these boots are lightweight and durable, offering exceptional abrasion resistance and natural movement. The soft microfiber front flex area enhances forward and backward mobility, ensuring a snug yet comfortable fit for demanding riding conditions. An accordion microfiber panel at the Achilles provides additional flexibility and improved natural movement, reducing fatigue during extended use. The exterior entry/exit design incorporates a stretchable accordion panel, facilitating easy on and off while maintaining a close fit for maximum control.
Alpinestars' unique Multi-Link Control system is evolved in this design to offer superior external ankle protection and support. It limits hyper-torsion, hyper-extension, and hyper-flexion, while also providing impact resistance to the Achilles and ankle areas. Safety is further enhanced with a replaceable dual-density TPU toe slider, which features a screw-in assembly for easy replacement and protective coverage around the outer toe. The boots also include a replaceable heel slider and an external side heel slider, strategically positioned to absorb shocks and facilitate sliding in case of a fall. Large asymmetrical accordion zones at the front and rear optimize flexibility, promoting maximum comfort and safety during dynamic riding.
The secure fit is maintained with a micro-adjustable ratchet top closure, which allows precise tightening and includes a stow tab for convenience. The advanced synthetic forefoot lining laminated with open-cell foam provides excellent shock absorption, while the highly breathable lining in the ankle and leg areas keeps the rider comfortable during long rides. An anatomical, replaceable EVA footbed offers arch support and a responsive pedal feel, enhancing overall riding precision. The durable rubber sole is textured for consistent grip, improving control and confidence on various surfaces. Inner instep speed lacing closure combined with a lateral zipper ensures a precise fit and quick donning. The innovative Lace-Lock System, made from advanced polymer resin, offers quick and secure closure, complemented by a hook-and-loop tab that keeps the zipper in place for added safety. A contoured high-modulus shin plate provides superior impact and abrasion resistance, completing the comprehensive protective features of this high-performance motorcycle boot.
