The Alpinestars SP-X BOA Boots are engineered for sport and sport touring riders seeking a versatile boot that balances protection, comfort, and style. Designed with a sleek, compact profile, these mid-height boots fit seamlessly under riding pants while offering excellent walking ability, making them an ideal choice for riders who value both on- and off-bike performance. Constructed from a combination of Rideknit® material and knitted mesh, the upper provides flexibility and breathability, while seamless thermo-welded sections ensure durability and a streamlined appearance.
For enhanced impact protection, the SP-X features a shin impact protector, dual-density ankle discs, and reinforced TPU shift pads and toe sliders. The sole incorporates an Alpinestars Transversal Protection Frame (TPF), offering superior impact resistance and torsional stability. The asymmetric back heel design promotes natural stride and improved off-bike stability, making these boots suitable for extended walking and daily commuting. The inclusion of a TPU heel counter and toe slider further enhances protection without sacrificing mobility.
Comfort is prioritized through strategically placed flex zones with knitted material, allowing free movement during riding and walking. The PU midsole with a double cushioned heel compound and removable OrthoLite® insock provide exceptional cushioning for long rides and daily use. Ease of entry and removal is facilitated by a medial zip combined with the BOA speed lace system, ensuring a secure and precise fit with minimal effort. These features make the Alpinestars SP-X BOA Boots perfect for sport riders who desire high-level protection and coverage without the bulk of full race boots, delivering a sleek, over-the-pant look suitable for various riding scenarios.
