Sizing: The Fusion 2.0 fits small. We'd recommend going a half size up from your usual size.
The Fusion 2.0 is a salute to the original Karhu ‘Fusion’ model from 1996 when it was the top running shoe in the collection. To bring back the ‘Fusion’ from the archives, Karhu reworked the model with its original designer and launched it as the Fusion 2.0. Made with leather and suede overlays, different kinds of mesh, printed detail on the front of the shoe, rope laces, pull tab, reflective details, and a speckled midsole.
