Shoe Review:KARHU Fusion 2021

Shoe: Karhu Fusion 2021

Category- Neutral Daily Trainer

Weight- 8.8 oz (W) 10.5 oz (M)

Heal to Toe Drop: 6 mm

Stack Height (Heel/toe): 24 mm / 18 mm

Preferred Surfaces: Track and Road

Cost: $140

My quick opinion: This has been one of the best updates I have seen by a shoe year to year. Karhu is a Fleet Feet Exclusive shoe and uses the 3D scans taken in store to design their shoes. The Fulcram through the midsole helps generate some needed motion for some. Overall I’m a big fan of this shoe and their HiVO option is great for people with “tall” feet(High instep Height)





  • Sold in limited locations
  • Lacks color options
  • Unique ride that some dont enjoy

Comparable shoe:

  1. Asics Numbus(~$150)
    • Similiar to the Karhu Fusion the Asics Nimbus has support through the midsole. The Nimbus is a slightly more cushioned model, falling into the premium cushion category
  2. Hoka Clifton (~$130)
    • Hoka Clifton also has a slight rocker to the bottom of the shoe. This shoe will offer a much more cushioned feel
  3. On Cloud Swift ($150)
    • Another rocker bottom shoe with a little more cushion. However this will be a slightly snugger fit

Who would I recommend the Karhu Fusion 2021 for?

This is a great shoe for someone looking for a daily trainer. This is a great hybrid shoe as it offers alittle more support than most neutral shoes but not a true stability shoes. Overall if you are looking for a little extra motion coming from you shoe and dont want a carbon plate this is the shoe for you
