KARHU Fusion Ortix 2020


The new Karhu Fusion Ortix is better than ever.

Redesigned with a sublimated engineered upper, the Fusion provides a seamless feel and secure fit without losing the stable landing and forward momentum of the previous model.

Underneath, the Fusion uses Karhu’s proprietary Aero Foam cushioning. The foam offers a lighter right a cushier feeling than typical EVA, and it’s more resistant to temperature changes.

Embedded into the midsole is Karhu’s signature fulcrum technology. The Fusion has a 3/4-length fulcrum that increases support in the middle of the and promotes a forward rolling effect.

Great Experience

We are in the midst of a pandemic that requires us to self-distance and that is stressful. Running is how I cope with stress and unfortunately my shoes were worn out and causing my shins some pain. I looked online for shoes, because I was unable to go in-store. I found out the exact model of my shoes and located it on Fleet Feet's website and realized they offered same day pick up. So helpful, especially since I had to go back the same day and exchange for a different size. The shoes are amazing and the staff at Fleet Feet of Mount Pleasant SO helpful. They answered all of my questions regarding fit and even looked into my past file to make sure I got the right size. They pulled the proper size and made it easy to switch out the shoes all in the same day. 10 out of 10 would highly recommend the shoes and the Mount Pleasant store for anyone in need of a good pair of running shoes.

Like wearing slippers!

These shoes are extremely comfortable, no breaking in required. On my second pair, and would buy more if there were any colors in my size!

Great replacement for Nike Pegasus

Love this shoe! The new Nike Pegasus does not work for me and this was the perfect replacement! This fits very similar to the older Pegasus style and fits true to size for my running shoes (half size up from street size). Fleet Feet Fox Valley employees introduced me to this shoe and I couldn't be happier. Great customer service there too!!

Great cushioning and support

Finally bought my very first pair of Karhus at our local Fleet Feet West Reading store and ran in them for the first time this morning. I was very impressed! From the moment I tried them on yesterday in the store, I knew I'd love them. Ran 4-1/2 miles this morning through streets and some light trails and the Fusion Ortiz felt awesome! I could tell there's a bit more cushioning and support than my other running shoes have. Definitely will be buying more if these prove to be as good and durable as I think they'll be!
