The Alpinestars SP-X Boa Drystar Boots are built for riders who put in serious miles and want lasting comfort without giving up protection or control. Designed around an ergonomically optimized sport-touring fit, these mid-length boots balance coverage and mobility for everyday touring and travel, while staying comfortable and natural to walk in off the bike.

A waterproof yet highly breathable Drystar liner helps keep your feet dry through changing conditions, and the rugged rubber sole is designed to deliver confident footing across pavement, gravel, and rest stops. For fast, precise on-the-fly adjustment, the lateral side entry system integrates the BOA Speed Lace System for a secure closure you can dial in quickly.
