The Alpinestars SP-X BOA motorcycle boots are designed for sport and sport-touring riders who want compact, mid-height coverage that fits comfortably under technical riding pants. The SP-X combines everyday walking comfort with dependable motorcycle protection, making it a practical choice for riders who need performance on the bike and mobility off it. This black EU 42 model is identified by manufacturer part number 2222024-1100-42 and vendor part number 2222024-1100-42.
The upper combines Rideknit® material, knitted mesh, and seamless thermo-welded components for a flexible, streamlined fit. Protection includes an integrated shin impact protector, dual-density ankle discs, a TPU heel counter, TPU shift-pad reinforcement, and a TPU toe slider. Alpinestars’ Transversal Protection Frame (TPF) in the sole helps resist impact, bending, and twisting while supporting stable foot positioning. The asymmetric rear heel promotes a natural stride and improves stability when walking away from the motorcycle.
Comfort-focused construction includes knitted flex zones at the front and rear, a PU midsole with an integrated dual-cushion heel compound, and a removable OrthoLite® insole for cushioned walking support. A medial zipper and BOA® speed-lace closure system make entry and exit simple while providing a precise, secure fit. The Alpinestars SP-X BOA boots are well suited to sport riders seeking protection and coverage without the bulk or height of a full race boot, especially when an under-the-pants fit is preferred.
