The Alpinestars SP-X Boa Drystar motorcycle boot is an ergonomically optimized, mid-length touring boot designed for riders who demand dependable comfort and protection during long-distance travel. This black and dark gray boot is sized at US 9.5 / EU 44 and features a waterproof, breathable Drystar membrane that helps keep feet dry in wet conditions while allowing moisture vapor to escape for improved comfort.
The main upper combines advanced microfiber, knitted mesh, and co-injected TPU with Lycra to balance flexibility, breathability, durability, and support. A lateral side-entry system uses BOA Speed Lace technology for quick, precise, and secure closure. The rugged rubber sole uses a specialized compound for reliable traction and impact absorption on varied surfaces, while the integrated support shank adds rigidity for motorcycle use. A high-flex inner structure improves walking comfort when off the bike.
Protection is built into the touring-focused design. TPU components reinforce the shift area, lateral toe box, and lateral calf, while the TPU heel counter provides impact protection and additional support. Dual-density ankle protectors are positioned between the upper and padded lining to help shield key impact areas, and internal shin reinforcement adds coverage beneath the upper. The Alpinestars SP-X Boa Drystar boot is suited for street, touring, and mixed on- and off-bike conditions where waterproof performance, walking comfort, secure fit, and riding protection are important.
