The Alpinestars SP-X BOA Boots in black and EU 40 are compact, mid-height sport motorcycle boots designed for riders who want protective coverage and comfortable walking performance without the bulk of a full race boot. Built for sport and sport-touring applications, these boots are designed to fit under technical riding pants and provide a streamlined over-the-pant look. The Rideknit® and knitted mesh upper uses seamless thermo-welded sections for flexibility, breathability, and a secure fit.
Protection is provided by an integrated shin impact protector, dual-density ankle discs, a TPU heel counter, TPU shift pad reinforcement, and a toe slider. The Alpinestars Transversal Protection Frame (TPF) in the sole helps resist impact and unwanted bending or twisting. An asymmetrical rear heel design supports the rider’s natural stride and improves stability when walking off the motorcycle. These features make the SP-X BOA a suitable choice for street sport riders and sport-touring riders who need dependable lower-leg and foot protection.
Comfort and convenience are supported by flexible knitted sections at the front and rear flex points, a PU midsole with an integrated dual-cushion heel compound, and a removable OrthoLite® insock. A medial zipper and BOA® speed-lace closure system allow quick entry and precise adjustment for a secure, compact fit. The Alpinestars SP-X BOA Boots, manufacturer part number and vendor part number 2222024-1100-40, are designed for riders seeking the balance of motorcycle protection, sport styling, and practical off-bike mobility.
