Our Verdict
Saucony Endorphin Azura
On Cloudmonster 3 Hyper
The On Cloudmonster 3 Hyper and Saucony Endorphin Azura are both plateless, cushioned shoes, but they target different parts of a rotation. The On leans more into cushioning with a taller stack height, creating a more protective, comfort-first ride that's better suited to recovery runs and relaxed mileage, though it can feel a bit more cumbersome. The Saucony is lighter and more versatile, with a more energetic PWRRUN PB midsole that makes it easier to pick up the pace and handle a wider range of efforts.
