Alpinestars SP-X BOA Boots - Black and Silver, EU Size 45

The Alpinestars SP-X BOA Boots are engineered for sport and sport-touring riders seeking a balance of protection, comfort, and style. Designed to fit seamlessly under riding pants, these boots combine a sleek profile with advanced features for optimal performance both on and off the bike. The upper is crafted from Rideknit® material and knitted mesh, with seamless thermo-welded parts that enhance durability and flexibility. This construction allows for excellent breathability and a snug, comfortable fit, making them suitable for extended riding sessions. The mid-height design offers ample coverage without the bulkiness of full race boots, giving riders a versatile option for various riding styles and conditions. The boots feature a TPU heel counter, toe slider, and the innovative Alpinestars Transversal Protection Frame (TPF) on the sole, providing high-impact protection while maintaining natural movement. The asymmetric back heel design improves off-bike stability and walking comfort, making these boots ideal for both riding and casual walking. For added impact resistance, the SP-X Boots include an integrated shin impact protector, dual-density ankle discs, and reinforced TPU shift pads and toe sliders. Comfort is further enhanced by flexible knitted zones at key points, allowing for natural foot movement. A PU midsole with a double cushioned heel compound, along with a removable OrthoLite® insock, ensures long-lasting comfort during extended wear. The boots are equipped with a medial zip and BOA® speed lace system, enabling quick, precise, and secure closure with minimal effort. These features, combined with a lightweight construction, make the Alpinestars SP-X BOA Boots a versatile choice for sport riders who prioritize coverage, protection, and comfort without the bulk of traditional race boots, offering a modern, over-the-pant look that suits both aggressive riding and casual wear.
