The Alpinestars SP-X BOA boots are compact, mid-height sport riding boots designed for riders who want dependable motorcycle protection with improved walking comfort. Sized in European 42, these black and silver boots fit beneath technical riding pants and are well suited for sport and sport-touring applications. The Rideknit® upper, knitted mesh, and seamless thermo-welded construction provide a flexible, streamlined fit for both on-bike performance and off-bike mobility.
Protection comes from the Alpinestars Transversal Protection Frame (TPF) integrated into the sole, which helps resist impact forces and excessive bending or twisting. The boots also feature a TPU heel counter, toe slider reinforcement, integrated shin impact protection, dual-density ankle discs, and a TPU shift pad. An asymmetric rear heel design supports a more natural stride and helps improve stability when walking. Flexible knitted sections at the front and rear flex points allow comfortable movement without sacrificing coverage.
A PU midsole with an integrated dual-cushion heel compound and removable OrthoLite® insole helps reduce walking fatigue during extended wear. Entry and adjustment are handled by a medial zipper and the BOA® speed-lacing system, providing quick, precise closure and a secure fit. The Alpinestars SP-X BOA boots, manufacturer part number and vendor part number 2222024-119-42, are a practical choice for sport riders who want more protection than casual riding footwear without the bulk and coverage of a full race boot.
