The Alpinestars SP-X BOA boots are compact, mid-height sport riding boots designed for riders who want dependable motorcycle protection with improved walking comfort. Sized for EU 41, these black boots are optimized for sport and sport-touring use and are designed to fit neatly under technical riding pants. The Rideknit® upper combines knitted mesh with seamless thermo-welded reinforcements for a flexible, streamlined fit, while the BOA® speed lace system and medial zipper provide quick, precise entry and closure.
Protection is built into the boot through an integrated shin impact protector, dual-density ankle discs, TPU heel counter, TPU shift pad, and reinforced toe slider. The Alpinestars Transversal Protection Frame (TPF) sole helps resist impact, bending, and twisting while supporting rider stability. An asymmetric rear heel design promotes a more natural stride when walking away from the motorcycle, making the SP-X BOA a practical choice for riders who need coverage without the bulk of a full race boot.
Comfort features include flexible knitted panels at the front and rear flex points, a PU midsole with an integrated double-cushioned heel compound, and a removable OrthoLite® insole for supportive off-bike walking. The all-new sole design balances motorcycle-ready protection with everyday mobility. The Alpinestars SP-X BOA boots are supplied in black, size EU 41, and are identified by manufacturer part number 2222024-1100-41 and vendor part number 2222024-1100-41.
