Alpinestars SP-X BOA Boots — EU 39, Mid-Calf, Black

SP-X BOA boots are a sleek sport boot engineered to sit under tech riding pants while delivering exceptional walking capability.

Optimized for sport and sport-touring riders, these compact, mid-height boots offer premium protection and comfort both on and off the bike. The upper combines Rideknit® material and knitted mesh with seamless thermo-welded panels for a streamlined, durable finish.

The lower incorporates a TPU heel counter, reinforced toe slider and a Transversal Protection Frame (TPF) in the sole to resist impacts and prevent harmful bending or twisting of the foot. The sole’s all-new asymmetric back heel encourages a natural stride and improves off-bike stability.

Protection features include an integrated shin impact protector, dual-density ankle discs, TPU shift pad and reinforced toe slider. Comfort comes from knitted flex zones at front and rear movement points, a PU midsole with a double-cushioned heel compound and a removable OrthoLite® insock for excellent walking comfort.

Entry and exit are fast and precise thanks to a medial zipper combined with the BOA speed lace system for compact, micro-adjustable closure. These boots suit riders who want coverage and protection without the full race-boot look.
