Alpinestars SMX Plus Motorcycle Boots - Black, US 5 / EU 38 - Model 2221019-10-38

The Alpinestars SMX Plus Boots are engineered for high-performance motorcycle riding, combining advanced protection with exceptional comfort. Constructed with an innovative microfiber upper, these boots offer a lightweight feel without compromising durability. The front flex area features a soft microfiber that enhances abrasion resistance while supporting natural forward and backward movement, ensuring comfort during extended rides. An accordion microfiber panel around the Achilles provides increased flexibility and natural ankle movement, critical for rider control and responsiveness. The exterior incorporates a stretchable accordion panel for easy entry and a snug fit, making them practical for everyday use.
The design incorporates Alpinestars' Multi-Link Control system, which delivers superior external support and protection for ankle articulation. This system effectively limits hyper-torsion, hyper-extension, and hyper-flexion, reducing injury risk while maintaining mobility. Additional protective features include a replaceable dual-density TPU toe slider with a screw-in assembly for durability, along with replaceable heel and side heel sliders designed to absorb shocks and facilitate sliding during falls. Large asymmetrical accordion zones at the front and rear optimize flexibility, ensuring maximum comfort and safety. The boots feature a micro-adjustable ratchet top closure with a stow tab, allowing for a customizable fit.
Comfort is further enhanced by the advanced synthetic forefoot lining laminated with open-cell foam, providing shock absorption and breathability. The ankle and leg areas are lined with highly breathable materials for added comfort during long rides. An anatomical, replaceable EVA footbed offers arch support and a precise pedal feel, complementing the overall ergonomic design. The durable sole is textured for consistent grip and improved riding control. For a secure fit, the boots include an inner instep speed lacing closure, a lateral zipper, and the innovative Alpinestars Lace-Lock System made from advanced polymer resin for quick, precise fastening. Hook and loop tabs secure the zipper pull, ensuring safety and a flat profile.
A high-modulus contoured shin plate provides superior impact and abrasion resistance, completing the protective package. These features make the Alpinestars SMX Plus Boots an ideal choice for riders seeking lightweight, versatile, and reliable motorcycle footwear that balances safety, comfort, and performance.
