Alpinestars SP-X BOA Boots — EU 46, US 11.5, Mid‑Calf, Black

The SP-X BOA boots are a sleek sport boot engineered to tuck under technical riding pants while offering superior walking capability.

• Compact, mid-height construction optimized for sport and sport-touring riders, balancing on-bike protection with off-bike mobility.
• The upper combines knit and mesh panels with seamless thermo-welded assemblies for flexibility and abrasion resistance.
• The lower shell features a reinforced heel counter, replaceable toe slider and a transversal protection frame in the sole for impact and torsion protection.
• The sole uses an asymmetric back heel to encourage a natural stride and boost stability when off the bike.
• Protection includes an integrated shin impact protector, dual-density ankle inserts and shift-pad reinforcement.
• Comfort comes from flexing knit zones, a cushioned midsole with dual heel compounds and a removable OrthoLite® insole for long walks.
• Entry is fast thanks to a medial zip paired with a BOA speed-lace system for compact, precise closure.

Ideal for sport riders who want coverage and protection without the full race-boot silhouette.
