Karhu fusion 4.0

Perfect fit for my workouts and treadmill.

Why did you change the design?

Jay L 2 months ago Verified Purchase

I received my fourth pair of Karhu Fusion shoes a few weeks ago. Unfortunately they changed the design and I'm not happy with them. I had three pairs before these and absolutely loved them. The new design feels bigger (always wore 10.5 with previous pairs) and not as cushy. :-(

Great Value

Fleet Feet offers great value for the price. The Karhu shoes where on sale, are excellent shoes and used my points to save $45!
