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. Sized at EU 47, these black boots are optimized to fit beneath technical riding pants while providing the walking comfort needed for off-bike use. The SP-X model is well suited for sport and sport-touring applications, combining a sleek profile with protective construction and a natural stride.
The upper combines Rideknit® material, knitted mesh, and seamless thermo-welded components for flexibility, airflow, and a secure fit. 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, bending, and twisting, while the asymmetric heel design improves off-bike stability and supports natural walking movement.
Comfort-focused features include knitted flex zones at the front and rear, a PU midsole with an integrated double-cushioned heel compound, and a removable OrthoLite® footbed. Entry and closure are simplified with a medial zipper and BOA® speed-lacing system, allowing compact, precise adjustment. Manufactured by Alpinestars and identified by vendor part number 2222024-1100-47, these SP-X BOA boots offer a practical balance of sport-oriented protection, flexible movement, and everyday riding comfort.
