Alpinestars SP-X BOA Boots — EU 48, US 12.5, Mid-calf, Black

The SP-X BOA is a sleek sport boot engineered to sit comfortably under tech riding pants while delivering superior walking capability. Designed for sport and sport-touring riders, it balances compact, mid-height coverage with high levels of protection and on- and off-bike comfort.

The upper combines Rideknit® material with knitted mesh and seamless thermo-welded panels to provide breathability and freedom of movement at key flex points. The lower shell integrates a TPU heel counter and toe slider, plus a Transversal Protection Frame (TPF) in the sole to resist impacts and prevent unwanted bending or twisting.

• Asymmetric back heel and new sole design for a natural stride and improved off-bike stability.
• Integrated shin impact protector, dual-density ankle discs, TPU shift pad and reinforced toe slider for robust impact protection.
• PU midsole with double-cushioned heel compound and removable OrthoLite® insock for enhanced walking comfort.
• Medial zip combined with the BOA speed lace system ensures compact, precise closure and easy entry.

Compact enough for riders who want protection without the full race-boot profile, the SP-X BOA delivers protection, comfort and a refined sport-oriented look.
