Alpinestars SP-X Boa Drystar® Boots - US 11.5 / EU 46, Black and Dark Gray

Designed for long-distance touring and demanding conditions, the Alpinestars SP-X Boa Drystar® Boots offer a perfect combination of comfort, protection, and waterproof performance. The mid-length touring design ensures ample coverage and support during extended rides, while the ergonomic shape reduces fatigue and enhances foot stability. Constructed with a blend of advanced microfiber, knitted mesh, and co-injected Thermoplastic Polyurethane (TPU) with Lycra, these boots deliver a lightweight yet durable fit with excellent breathability and flexibility. The innovative combination allows riders to stay comfortable in varying weather conditions without sacrificing mobility or support.
The waterproof Drystar® membrane guarantees exceptional wet weather performance by keeping feet dry while allowing moisture vapor to escape, ensuring a breathable environment inside the boot. The rugged rubber sole features a textured grip and shock-absorbing properties, making it suitable for diverse terrains both on and off the bike. An integrated support shank enhances sole rigidity for added stability, while the high-flex inner structure of the sports sole provides superior walking comfort. The lateral side entry system incorporates BOA Speed Lace System technology for quick, precise, and secure closure, allowing easy adjustment even with gloves.
Protection features include strategically positioned TPU sliders on the lateral toe-box and calf for flexibility and impact resistance, a TPU heel counter for impact absorption and support, and dual-density ankle protectors layered between the upper and padded lining for strategic impact protection. Internal shin reinforcement adds extra defense in critical areas, and the shift pad with TPU technologies offers superior upper foot protection. Overall, the Alpinestars SP-X Boa Drystar® Boots are engineered to meet the demands of serious riders seeking reliable performance, comfort, and protection across all riding conditions.
