The Alpinestars SP-X BOA boots are compact, mid-height sport riding boots designed for riders who want dependable protection, comfortable walking performance, and a streamlined fit under technical riding pants. Finished in black and silver, these EU 43 boots combine Rideknit® material, knitted mesh, and seamless thermo-welded components for a flexible, supportive upper suited to sport and sport-touring use. The over-the-pant profile provides coverage without the bulk of a full race boot.
Protection features include an integrated shin impact protector, dual-density ankle discs, a TPU heel counter, TPU shift-pad reinforcement, and a toe slider. The Alpinestars Transversal Protection Frame (TPF) integrated into the sole helps resist impact, bending, and twisting while supporting rider stability. The asymmetric rear heel design promotes a natural stride and improves off-bike footing. The PU midsole incorporates a double-cushioned heel compound, while the removable OrthoLite® insole enhances comfort during walking and extended wear.
A medial zipper and BOA® speed-lace closure system make entry, exit, and adjustment quick and precise. Knitted flex zones at the front and rear improve freedom of movement while maintaining a secure fit for active riding. The Alpinestars SP-X BOA boots are a strong choice for sport and sport-touring riders seeking everyday versatility, compact coverage, and motorcycle-specific protection. This product is size EU 43, equivalent to approximately US men's 9.5, and is identified by manufacturer and vendor part number 2222024-119-43.
