Beginner
The Fusion 5.0's lightweight build and lower stack may be challenging for beginners. 26mm heel cushioning is on the thinner side, requiring some running fitness and technique. The short Fulcrum unit provides snappy response suited for runners with a base looking to improve speed. Beginners should start with the more cushioned Ikoni 3.5 first.
