The Alpinestars SP-X BOA boots are compact, mid-height sport riding boots designed for riders who want dependable motorcycle protection, precise fit, and comfortable walking performance. This black EU 38 model is designed to fit under technical riding pants and is well suited for sport and sport-touring applications. Manufactured by Alpinestars, the boots combine Rideknit® material, knitted mesh, and seamless thermo-welded construction for a streamlined fit and flexible comfort.
Protection is provided by 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) integrated into the sole helps resist impact forces and excessive bending or twisting. An asymmetric rear heel supports a natural stride and improves stability when walking off the motorcycle. The sole design delivers a practical balance of riding protection and everyday mobility without the bulk of a full race boot.
Comfort and closure are optimized for extended use on and off the bike. Knitted flex areas at the front and rear allow natural movement, while the PU midsole with an integrated cushioned heel compound and removable OrthoLite® insole helps provide walking comfort. A medial zipper works with the BOA® speed-lace system to provide quick entry and a secure, precise closure. The Alpinestars SP-X BOA boots are an effective choice for sport riders seeking over-the-pant coverage, protective features, and versatile off-bike performance.
