Features
The Karhu Fusion delivers unbeatable cushion and fast transitions to your everyday runs.
Built on top of Karhu’s unique AeroFoam midsole, the Fusion is lightweight and more temperature resistant than shoes built with EVA midsole foam. Maximum cushioning in the forefoot creates super-soft landings while an added propulsion unit energizes take-offs.
A shortened, 3/4-length Fulcrum embedded in the midiole of the Fusion concentrates cushioning toward the heel and midfoot, creating a responsive rocker that stabilizes each step and pushes you forward.
The upper is constructed from Karhu’s super-breathable, lightweight Ideal Knit mesh that supports your foot on top of the midsole for an all-around comfortable fit.
Karhu also created a high-volume option for wider feet. The Fusion HiVo provides a wide width for runners who need a little more space.

What's New
While the nuts and bolts of the Karhu Fusion Ortix 2021 are the same as previous versions, the new edition is lighter with a sleeker upper to shed ounces. The AeroFoam midsole is as cushy as ever, but the adjusted Fulcrum and propulsion unit create a faster transition in this version than the previous models.

Why You'll Love It
Great for everyday training or road races, the Fusion Ortix 2021 is a versatile shoe that provides plush cushioning and quick transitions.

Karhu Fusion
This is my first purchase of the Karhu Fusion shoe. I've previously purchased the IKoni and loved it but thought I'd try the Fusion . Karhu never disappoints. It has proven to be the best shoe for my feet. The sales help was extremely helpful in ordering them for me since the store was out of my size.

Karhu Fusion
I have suffered with plantar fasciitis for years. Fleet Feet recommended Karhu Fusion. Absolutely the best shoes I have ever owned! I have not had an issue with foot pain since I began wearing them. They are well made and lightweight. The only shoe I will ever need!

Disappointed with V3 Fusion Ortiz
Loved the Fusion 2021 HiVO sneaker ordered again and received the V3 version. I learned the heel drop has changed from 10mm to 6mm which has negatively impacted my runs. I will be returning these although I love this brand and the fit of the shoe. Hoping Karhu puts out more neutral running shoes with 8-10mm heel drop. I also understand it can take months to adapt to a different (lower) heel drop by using various shoes for each run but just prefer to get something that I know works for me so I can fully enjoy my runs. I am appreciating the 60-day return policy as well.

Women's | KARHU Fusion 2021
I have tried at least a dozen different brands over the past several years and I have to say that the Women's I KARHU 2021 is the most comfortable walking shoe I have ever own so I went back to Fleet Feet to purchase a second pair as a back up! Love them and would highly recommend them to anyone looking for comfort!

Awesome shoes
I love these shoes!! They are super light and have really helped with my sciatica pain. Most shoes I can't wait to get off but these I can go all day and not think about them.

love these sneakers
I needed to re-order the HiVo version of these shoes b/c I had issues w/my left big toe mound. And also had to take out the insert that comes with the shoe and replace with an insert for arch support without extending into the toes to give them more room. This worked and my runs are awesome. My pace has improved. Love the cushion. Other than needing more toe space the fit is incredible. my foot feels supported and wraps around the top of my foot feels super comfortable. My toe issue is improving and probably needed these new sneakers a lot sooner and I could have avoided this issue.
