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.

Great quality, but disappointing returns experience
I sized down when ordering the Karhu Fusion 2, but the trainers were still too large. I returned them 7 days ago and have yet to receive any confirmation that the return has been received or that my refund is being processed.
It’s a shame because the trainers themselves appear to be very good quality, well finished and solid. Unfortunately, the lack of communication regarding the return and refund has let the overall experience down.

Second pair of these beauties this year. One for my partner and one for me and we love them.
