The Alpinestars SP-X BOA is a mid-height sport riding boot built for sport and sport-touring riders who want real protection without a full race boot. The upper mixes Rideknit knit mesh with thermo-welded panels, backed by a shin protector, dual-density ankle discs, a TPU heel counter, a shift pad and a toe slider. A Transversal Protection Frame in the sole resists bending and twisting, while the PU midsole, double-cushion heel and removable OrthoLite insole target off-bike comfort. Against full race boots it trades some rigidity for walkability and a lower profile that tucks under riding pants; the BOA dial and medial zipper make it quicker to put on than laced or buckled rivals.

The Alpinestars SP-X BOA is a compact, mid-height sport riding boot for sport and sport-touring riders. It gives coverage and protection without the bulk of a full race boot. It fits under technical riding pants and keeps a streamlined look over the pants.
The upper combines Rideknit® material, knitted mesh and seamless thermo-welded panels for flexibility, ventilation and a close fit. Protection includes an integrated shin impact protector, dual-density ankle discs, a TPU heel counter, TPU shift pad reinforcement and a toe slider. The Transversal Protection Frame (TPF) in the sole helps resist impact forces, excessive bending and twisting.
A PU midsole with an integrated double-cushion heel compound and a removable OrthoLite® insole add comfort during extended wear. Knitted flex zones at the front and rear allow natural movement on and off the bike. An asymmetrical rear heel design supports a natural stride and stability when walking. A medial zipper and BOA® speed-lacing system make entry and closure quick and precise.
