Karhu continues to design its footwear collection based on a growing 3D foot scan database.The Fusion Ortix becomes the second Karhu shaped by fit id™ and is updated with fall colors.
The most notable update comes with a seamlessly engineered mesh upper for increased comfort and a better fit.
A narrower heel, reduced forefoot volume, and fewer overlays ensure the Fusion Ortix fits the average shape of runners' feet.
The M-lock lacing cords help to securely wrap the midfoot while the reshaped forefoot provides comfort at the toes.
Featuring a three-quarter length fulcrum, the Fusion Ortix provides supportive guidance through the gait cycle.
Built on a relatively lightweight, yet durable platform, the Fusion Ortix excels at providing just the right amount of comfort and stability.
