Paraphrased from published reviews.

What's new in each

On Cloudmonster 3: A new triple-layer CloudTec midsole and a reworked upper that fixes the Cloudmonster 2's awkward fit. Stack is almost unchanged; drop rises slightly to 6 mm.

On Cloudsurfer 3: Surreal supercritical foam replaces Helion for a softer, bouncier ride, with a plusher warp-knit upper and wider base; it is noticeably heavier than the Cloudsurfer 2 at the same price.
