The HOKA Kaha 2 GTX is a running shoe/hiking boot hybrid. Supportive and protective like a boot, lightweight and cushioned like a running shoe. For extended treks with variable weather and terrain, the Kaha is ready for it all. With an exceptional cushion-to-weight ratio, waterproof leather uppers, and the Vibram Megagrip, this is an excellent option for early or late-season Sierra treks like the Evolution loop!
