Out of stock
UNISEX SIZE IN US MEN'S
SKU_F804037
In 1996, the Karhu “Fusion” model was the top running shoe in the collection. To bring it back from the archives, Karhu reworked the model with its original designer launching it as the Fusion 2.0. After a successful 2015 introduction, Karhu felt it was time to honour the Fusion by releasing a version inspired by the shoe’s original details. The Fusion 2.0 “OG” differentiates in look from the existing inline version to deliver an authentic aesthetic.

The sport of track and field is close to Karhu’s heart. Across the decades, Karhu has appeared on podiums at the Olympics, national and at collegiate championships. In the release features the Fusion 2.0 in soft grey suede and o white tones creating a sporty look. Before all-weather surfaces were installed at most track complexes, grey cinders with white chalk lines were the most commonly found.
