The Alpinestars SP-X BOA Drystar Boot is a mid-length touring motorcycle boot designed for comfortable, confident riding over long distances. This Black/Dark Gray boot is offered in US 5/EU 38 and features an ergonomically optimized design that supports both on-bike performance and off-bike walking comfort. The waterproof and breathable Drystar membrane helps keep feet dry in wet conditions while allowing moisture vapor to escape for improved comfort during changing weather.
Built with a combination of advanced microfiber, knitted mesh, and co-injected TPU with Lycra, the upper balances flexibility, breathability, durability, and support. A lateral side-entry system with BOA Speed Lace technology enables quick, precise, and secure closure. The rugged rubber sole uses a specialized compound for reliable traction and impact absorption, while an integrated support shank increases sole rigidity. The sports sole design includes a high-flex inner structure for easier walking and all-day touring comfort.
Protection is integrated throughout the Alpinestars SP-X BOA Drystar Boot. TPU technology reinforces the shift pad for added upper-foot coverage, while TPU sliders on the lateral toe box and calf support controlled flexion and impact resistance. A TPU heel counter provides additional support and protection, and dual-density ankle protectors are positioned between the upper and padded lining for targeted coverage. Internal shin reinforcement adds protection in a critical impact area without compromising the boot's practical touring design.
