These high-velocity hikers look and perform like no KEEN® shoe you've ever seen. First there's the new athletic fit – streamlined, yet with the iconic wide toe box that lets your forefoot spread for superior traction and stability. The ripstop mesh upper resists scrapes and scuffs, and the KEEN.DRY® breathable bootie keeps feet dry from the inside out. A high-energy footbed lets your feet bounce off the trail, fighting fatigue as you rack up the miles. Under it all, a re-engineered lugged rubber outsole digs in uphill and downhill in any terrain. Best of all, the Zionic is built with water-based adhesives and recycled, PFAS-free materials to tread more lightly on the only Earth we've got.
