There The men's Karhu Fusion Ortix is a high-cushion running shoe for runners with neutral foot. With a soft yet propulsive ride, it's ideal for performance-oriented athletes who are looking for a shoe for fast training or for race day.
There new Fusion for men is lighter than previous versions and maintains a touch of heel support providing an even quicker transition. The updated upper has reduced weight while maintaining a secure fit. There Fusion now features a shortened Fulcrum, the shortest in the collection, and a unit of propulsion for an even faster sensation. In the end, Extra cushioning is added to the forefoot for added protection in the process of detachment.
In Karhu, we know that every runner has unique feet, and this is exactly what he brought up to the new Fusion Ortix. Fusion Ortix is built from a growing database of more than 1.3 million 3D scans taken from the runners' feet.
