The Alpinestars SP-X BOA boots are compact, mid-height sport riding boots designed for riders who want dependable protection and walking comfort without the bulk of a full race boot. This black EU 46 model is optimized for sport and sport-touring applications, with an over-the-pant profile that fits comfortably beneath technical riding pants. The sleek design provides practical coverage on and off the motorcycle while supporting a natural walking stride.
The upper combines Rideknit® material, knitted mesh, and seamless thermo-welded reinforcements for flexibility and durability. Protection includes an integrated shin impact protector, dual-density ankle discs, a TPU heel counter, TPU shift-pad reinforcement, toe slider reinforcement, and the Alpinestars Transversal Protection Frame (TPF) integrated into the sole. These components help guard against impacts while limiting excessive bending and twisting of the foot and ankle.
Comfort and mobility are supported by knitted flex zones at the front and rear, a PU midsole with a double-cushioned heel compound, and a removable OrthoLite® insole. The asymmetric rear heel promotes a natural stride and improves stability when walking away from the motorcycle. A medial zipper and BOA® speed-lacing system provide efficient entry, secure adjustment, and a compact closure for a precise fit.
