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

• Compact, mid-height construction optimized for sport and sport-touring riders, offering premium protection and comfort on and off the bike.
• Upper combines Rideknit® material and knitted mesh with seamless thermo-welded parts for a streamlined profile and flexibility.
• The lower features a TPU heel counter, toe slider, and the Alpinestars Transversal Protection Frame (TPF) in the sole to guard against impacts and resist bending or twisting.
• An all-new sole design includes an asymmetric back heel to support the rider's natural stride and improve off-bike stability.
• Integrated shin impact protector, dual-density ankle discs, TPU shift pad and toe slider reinforcement maximize on-bike protection.
• Knitted flex zones at front and back increase freedom of movement, while a PU midsole with dual-cushioned heel compound and a removable OrthoLite® insock provide excellent walking comfort.
• Entry and exit are quick and precise thanks to a medial zip paired with the Boa speed lace system for compact closure. ⚙️
• Perfect for sport riders seeking coverage and protection without the full race-boot silhouette.
