The Alpinestars SP-X Boa Drystar Boot is a mid-length touring motorcycle boot designed for riders who demand comfort, protection, and dependable weather performance on long-distance rides. This black and dark gray boot is sized for US 8 / EU 42 and features an ergonomically optimized touring design that supports comfort in the saddle and while walking.
The waterproof and breathable Drystar membrane helps keep feet dry in wet conditions while allowing moisture vapor to escape for improved interior comfort. The lateral side-entry closure uses BOA Speed Lace System technology for quick, precise, and secure adjustment. The upper combines advanced microfiber, knitted mesh, co-injected TPU, and Lycra to balance breathability, flexibility, durability, and support. A Drystar liner provides all-weather performance without sacrificing ventilation.
Protection is integrated throughout the boot with dual-density ankle protectors, internal shin reinforcement, a TPU heel counter, TPU sliders at the lateral toe box and calf, and a TPU shift pad for enhanced upper-foot protection. The rugged rubber sole uses a grippy compound for traction and impact absorption, while the integrated support shank improves sole rigidity. A high-flex inner structure enhances walking comfort, making the SP-X Boa Drystar suitable for touring, commuting, and varied on- and off-bike conditions.
Manufactured by Alpinestars and supplied under vendor part number 2242025-111-42, the SP-X Boa Drystar Boot combines motorcycle-specific protection with everyday touring usability. Its secure closure, waterproof construction, supportive sole, and protective chassis make it a practical choice for riders seeking reliable performance across changing weather and terrain.
