Alpinestars SP-X BOA Boots — EU 44, US 9.5, Mid-Calf, Black

These sleek sport boots are engineered to sit comfortably under tech riding pants while delivering superior walking capability.

• Compact, mid-height construction optimized for sport and sport-touring riders to offer premium protection and on/off-bike comfort.
• The upper pairs Rideknit® material with knitted mesh and seamless thermo-welded panels for a lightweight, flexible fit.
• The lower incorporates a TPU heel counter, toe slider, and the Transversal Protection Frame (TPF) in the sole to guard against impacts and resist bending or twisting.
• An asymmetric back heel and redesigned sole promote a natural stride and enhanced off-bike stability.
• Protection features include an integrated shin impact protector, dual-density ankle discs, TPU shift pad, and reinforced toe slider.
• Comfort is boosted by knitted flex zones at front and back points, a PU midsole with an integrated double-cushioned heel compound, and a removable OrthoLite® insock.
• A medial zip combined with the BOA speed lace system ensures quick, compact, and precise closure.

Ideal for sport riders seeking coverage and protection without the full race-boot, over-the-pant aesthetic.
