The Alpinestars SP-X BOA boots are compact, mid-height sport motorcycle boots designed for sport and sport-touring riders who want dependable protection with comfortable off-bike mobility. Sized at EU 43, these black boots are designed to fit under technical riding pants while providing coverage and support without the bulk of a full race boot. The Rideknit® upper combines knitted mesh with seamless thermo-welded reinforcement for a flexible, streamlined fit.
Protection: The SP-X BOA incorporates 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 protect against impacts while limiting harmful bending and twisting. An asymmetric rear heel supports a natural walking stride and improves stability when moving off the motorcycle.
Comfort and Closure: Knitted flex zones at the front and rear promote freedom of movement, while the PU midsole includes a dual-cushion heel compound for improved walking comfort. A removable OrthoLite® insole adds cushioning and breathability. The medial zipper and BOA® speed-lace system provide quick entry and a precise, secure closure that keeps the boot compact under riding pants.
These Alpinestars SP-X BOA boots are suited to riders seeking sport-oriented styling, everyday versatility, and enhanced protection for street and sport-touring use. The manufacturer part number and vendor part number are 2222024-1100-43, identifying the black EU 43 configuration.
