Limited Edition, Great Color. Taking its name from the Māori word for strength and support, the All Gender Kaha Mid delivers on both, making uphill climbs easier and downhill descents faster. Remarkable in its weight-to-cushion ratio, the Kaha Mid GTX offers the full HOKA package — combining proprietary foams, patented geometries, exceptional Vibram® Megagrip traction and an adjustable lacing system for foot lockdown. Soft and smooth, yet inherently supportive, the new Kaha Mid GTX features the same GORE-TEX bootie as the original, designed to keep feet comfortable and dry in any forecast. Hike on, the trail awaits.
