ALPINESTARS SP-X BOA Drystar® Boots

Ergonomically optimized for touring, the mid-length SP-X BOA Drystar® Boot is engineered to deliver exceptional comfort over long miles in the saddle. The waterproof and breathable Drystar® membrane provides reliable wet-weather performance, while the grippy, rugged sole is built to excel across varied conditions and terrains, on and off the bike.

The lateral side-entry system incorporates BOA® Speed Lace System technology for quick, precise and secure closure. The main upper combines advanced microfiber, knitted mesh and co-injected Thermoplastic Polyurethane (TPU) with Lycra for an ideal balance of comfort, breathability and performance. A Drystar® liner helps maintain waterproof protection while allowing the boot to remain highly breathable.

The rubber sole uses a specialized compound for textured grip and excellent shock absorption, with an integrated support shank for enhanced sole rigidity. A high-flex inner structure and lasting insole provide superior walking comfort, making this motorcycle touring boot practical both on and off the bike.

TPU shift-pad technology delivers enhanced upper-foot protection, while strategically positioned TPU sliders on the lateral toe box and lateral calf support flexion and protection. A TPU heel counter provides impact protection, support and security. Dual-density ankle protectors are positioned between the upper and padded lining for targeted protection, and internal shin reinforcement is layered beneath the upper for impact protection in a critical area.
