On Cloudmonster 3 vs Vivobarefoot Primus Lite IV
Sqwod verdict
Our pick: On Cloudmonster 3 takes it — 77 vs 74.
Both are strong — the call comes down to what you prioritise:
- On Cloudmonster 3 — You coach neutral runners who like a firm, rockered max-stack trainer and want On's build quality for easy and long miles.
- Vivobarefoot Primus Lite IV — Buy if you want maximum ground feel for lifting, functional training and hard gym floors, and you or your clients are already used to barefoot shoes.
Our pick 
On Cloudmonster 3
77Score · Medium
from €140
A refined Cloudmonster with a better upper and a smoother roll, but the same heavy, firm Helion ride. Buy it for On's rocker and build quality, not for bounce.
Vivobarefoot Primus Lite IV
74Score · Low
from €97
The Primus Lite IV keeps the class-leading ground feel of the III in a lighter, more resource-efficient build. Early reviews flag weaker durability and grip, and crowd data is still thin.
