The Alpinestars SP-X Boa Drystar Boot is a mid-length touring boot designed for riders who demand comfort, protection, and dependable weather performance over long miles. This black and dark gray boot is sized US 6/EU 39 and features the Alpinestars Drystar® waterproof and breathable membrane, helping keep feet dry in wet conditions while allowing moisture vapor to escape for improved comfort. Its versatile construction is suited for touring, commuting, and varied riding conditions both on and off the motorcycle.
The main upper combines advanced microfiber, knitted mesh, and co-injected thermoplastic polyurethane (TPU) with Lycra to balance flexibility, breathability, durability, and support. A lateral side-entry closure uses the BOA® Speed Lace System for quick, precise, and secure adjustment. The rugged rubber sole uses a specialized compound for reliable traction and shock absorption, while the integrated support shank improves sole rigidity. A high-flex inner structure enhances walking comfort when riders are off the bike. The TPU shift pad helps protect the upper foot during gear changes.
Protection is integrated throughout the boot, including strategically positioned TPU sliders at the lateral toe box and lateral calf, a TPU heel counter for impact protection and support, dual-density ankle protectors, and internal shin reinforcement beneath the upper. The Drystar® liner supports all-weather performance, while the padded lining and ergonomic touring design promote comfort during extended rides. The Alpinestars SP-X Boa Drystar Boot, manufacturer part number and vendor part number 2242025-111-39, is designed for riders seeking a secure, waterproof touring boot with everyday walking flexibility and motorcycle-specific protection.
