The Alpinestars SP-X BOA Boots in Black/Silver are compact, mid-height sport riding boots designed for sport and sport-touring riders who want dependable protection without the bulk of a full race boot. Sized at EU 44, these boots are designed to fit beneath technical riding pants while providing comfortable walking performance off the motorcycle. The Rideknit® and knitted mesh upper uses seamless thermo-welded construction for flexibility, durability, and a streamlined over-the-pant fit.
Protection is built into the lower structure with a TPU heel counter, toe slider, TPU shift pad reinforcement, integrated shin impact protector, and dual-density ankle discs. The Alpinestars Transversal Protection Frame (TPF) in the sole helps resist impact, bending, and twisting while supporting stability during riding and walking. An asymmetric rear heel design promotes a natural stride and improved off-bike balance. These features make the SP-X a practical choice for riders seeking coverage and protection in a more compact sport boot.
Comfort and adjustability come from knitted flex zones at the front and rear, a PU midsole with an integrated double-cushioned heel compound, and a removable OrthoLite® insole for supportive walking comfort. A medial zipper works with the BOA® speed-lace system to provide quick entry and precise, compact closure. The Alpinestars SP-X BOA Boots are suitable for sport and sport-touring applications and are intended for riders who want protective footwear that transitions easily between motorcycle use and everyday movement.
