The Alpinestars SP-X BOA boots are compact, mid-height sport riding boots designed for riders who want dependable coverage and protection without the bulk of a full race boot. Built for sport and sport-touring use, the Black/Silver SP-X boots fit comfortably under technical riding pants while maintaining a streamlined over-the-pant appearance. This EU 39 model is identified by Alpinestars part number 2222024-119-39 and combines practical off-bike walking comfort with motorcycle-specific protection.
Feature: The upper combines Rideknit® material, knitted mesh, and seamless thermo-welded panels for flexibility, ventilation, and a close-fitting profile. Protection includes 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) in the sole helps resist impact forces as well as excessive bending and twisting, while the asymmetrical rear heel design supports a natural stride and improved stability when walking.
Feature: A PU midsole with an integrated double-cushion heel compound and removable OrthoLite® insole enhance comfort during extended wear. Knitted flex zones at the front and rear allow natural movement on and off the motorcycle. Entry and adjustment are simplified with a medial zipper and BOA® speed-lacing system, providing quick, precise closure. The SP-X BOA is a practical choice for riders seeking sport-oriented protection, everyday usability, and a lower-profile alternative to full-height racing boots.
Fitment: Designed for sport and sport-touring riders, the Alpinestars SP-X BOA boots are suitable for motorcycle use with technical riding pants and compatible riding gear. Manufacturer and vendor part number: Alpinestars 2222024-119-39.
