Alpinestars SP-X BOA Motorcycle Boots - Black and Silver, EU Size 42

Designed for sport and sport-touring riders, the Alpinestars SP-X BOA boots combine sleek styling with advanced protection and comfort. These mid-height boots are engineered to fit seamlessly under riding pants, offering a streamlined look without sacrificing safety or mobility. The upper features a combination of Rideknit® material and knitted mesh, along with seamless thermo-welded sections, providing a lightweight yet durable exterior that adapts well to foot movement. The innovative design ensures maximum flexibility in the front and back flex zones, promoting natural foot motion during riding and walking.
The sole is constructed with a TPU heel counter, toe slider, and the Alpinestars Transversal Protection Frame (TPF), which delivers high impact resistance and stability against twisting or bending forces. The asymmetric back heel design enhances off-bike stability, making walking and maneuvering easier. For added protection, these boots incorporate an integrated shin impact protector, dual-density ankle discs, and reinforced TPU shift pads and toe sliders. These features collectively safeguard critical areas against impacts and abrasions.
Comfort is a priority with the SP-X boots, featuring a PU midsole with a double cushioned heel compound, a removable OrthoLite® insock, and knitted zones that allow freedom of movement. Fast and secure closure is achieved through a medial zip combined with the BOA speed lace system, providing precise and compact fastening. Whether you're on the track or enjoying spirited rides, these boots provide coverage and protection without the bulk of full race boots, offering an over-the-pant look that balances style, safety, and comfort for the modern sport rider.
