Sizing: The Fusion 2.0 style runs small. We'd suggest going a half size up when trying on this shoe. IE, if you usually wear a women's 8.5, we'd suggest a women's 9 in this style.
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.
