Alpinestars SP-X BOA Boots — EU 47, US 12, Mid-Calf, Black

Compact sport-touring boots designed to fit under technical riding pants while offering superior walking capability and protection.

• Optimized for sport and sport-touring riders: compact, mid-height profile that balances protection with off-bike mobility.
• The upper combines Rideknit® material and knitted mesh with seamless thermo-welded panels for durability and flexible movement.
• The lower features a TPU heel counter, toe slider and a Transversal Protection Frame (TPF) on the sole to resist impacts and prevent bending or twisting.
• An all-new sole design with an asymmetric back heel promotes a natural stride and improves stability when walking off the bike.
• Protection includes an integrated shin impact protector, dual-density ankle discs, plus TPU shift pad and reinforced toe slider.
• Comfort is delivered by knitted flex zones at key points, a PU midsole with a double-cushioned heel compound and a removable OrthoLite® insock for long-wearing comfort on foot.
• Entry and exit are quick and precise thanks to a medial zip paired with the BOA speed lace system for compact, adjustable closure.
• Material composition: 36% microfiber, 24% polyurethane, 21% polyester and 19% TPU. Lining: 61% polyester, 28% synthetic and 11% microfiber.

Ideal for riders who want coverage and protection without the bulk of a full race boot.
