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

SP-X BOA boots are a sleek sport boot designed to fit under tech riding pants while delivering superior walking capability.

Optimized for sport and sport-touring riders, the SP-X are compact, mid-height boots that blend premium protection and comfort on and off the bike.

• Upper combines Rideknit® fabric and knitted mesh with seamless thermo-welded panels for a close, flexible fit.
• Lower construction includes a TPU heel counter, reinforced toe slider and the Transversal Protection Frame (TPF) in the sole to resist impacts and prevent bending or twisting.
• The sole features an asymmetric back heel that supports a natural stride and promotes off-bike stability.
• Integrated shin impact protector, dual-density ankle discs, TPU shift pad and toe-slider reinforcement enhance on-bike protection.
• Knitted flex points, a PU midsole with a double-cushioned heel compound and a removable OrthoLite® insock provide excellent walking comfort.
• A medial zip paired with the BOA speed lace system offers compact, precise closure for quick on-and-off.

Designed for riders who want coverage and protection without the full race-boot look, the SP-X delivers a balanced mix of performance, protection and everyday wearability.
