The SP-X BOA is a mid-height sport and sport-touring motorcycle boot built to sit under riding pants. It pairs a Rideknit and knitted mesh upper with an integrated shin protector, dual-density ankle discs, a TPU heel counter, shift pad and toe slider, plus an Alpinestars Transversal Protection Frame in the sole. A medial zipper and BOA speed-lace dial give quick entry and fine adjustment. It suits street sport and sport-touring riders who want real protection with easier walking than a full race boot, though it offers less coverage than a track-focused boot.

The Alpinestars SP-X BOA is a compact, mid-height sport motorcycle boot. It gives protective coverage and comfortable walking performance without the bulk of a full race boot. It is made for sport and sport-touring riding and fits under technical riding pants.
The upper is Rideknit® and knitted mesh with seamless thermo-welded sections for flexibility, breathability and a secure fit. Protection comes from 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.
A medial zipper and a BOA® speed-lace system allow quick entry and precise adjustment. Flexible knitted sections at the front and rear flex points, a PU midsole with a dual-cushion heel compound, and a removable OrthoLite® insock add comfort. The asymmetrical rear heel design supports the rider's natural stride and improves stability when walking off the bike.
