The Alpinestars SP-X Boa Drystar motorcycle boots are designed for touring riders who demand lasting comfort, dependable weather protection, and secure support on extended journeys. This mid-length boot features an ergonomic touring design and a waterproof, breathable Drystar membrane that helps keep feet dry in wet conditions while allowing moisture vapor to escape. The black and dark gray finish delivers a versatile look suitable for everyday riding and long-distance touring.
The upper combines advanced microfiber, knitted mesh, and co-injected thermoplastic polyurethane with Lycra to balance breathability, flexibility, and durability. A lateral side-entry closure uses BOA Speed Lace System technology for fast, precise, and secure adjustment. The Drystar liner supports all-weather performance, while the rugged rubber sole uses a specialized compound for dependable grip and shock absorption on pavement, uneven surfaces, and off-bike walking. A high-flex inner structure improves walking comfort without sacrificing support, and the integrated shank adds sole rigidity for controlled foot placement.
Protection is built into the SP-X Boa Drystar boot with a TPU shift pad, lateral toe-box and calf sliders, a reinforced TPU heel counter, dual-density ankle protectors, and internal shin reinforcement. These components help protect key impact zones while preserving the flexibility needed for motorcycle control. The boot is designed to fit riders seeking a comfortable, waterproof touring option with practical protection for street, touring, and mixed on- and off-bike use.
