On Cloudmonster 2 Pleasures x The Loop vs On Cloudmonster 3 Hyper:
Which to Choose

The clearest split is the midsole philosophy. The Cloudmonster 2 embeds a composite Speedboard — a stiffening shank, not a carbon racing plate — over standard Helion foam, which gives it a lively, snappy toe-off that firms up and rewards you as you push the pace. The Cloudmonster 3 Hyper throws the Speedboard out entirely and instead leans on a more premium PEBA-based Helion HF foam and pure rocker geometry for propulsion, so its bounce comes from the foam rather than from plate stiffness. That shows up in the cushioning and geometry numbers: the Hyper is a genuinely max-cushioned shoe (6/6) sitting on a tall ~43 mm heel / 34 mm forefoot stack, versus the 2's above-average cushioning on a lower ~34.5 mm / 29 mm platform. Drop is a real divider too — the 2 runs a low ~4 mm offset that keeps you mid-to-forefoot, while the 3 Hyper's measured 9 mm (On markets it as 6 mm) eases strain toward the heel and will suit heel-strikers better. Counterintuitively, the taller, more cushioned Hyper is also the lighter shoe, coming in at 264 g (men's US 9) against roughly 295 g for the Cloudmonster 2, so you're not paying a weight penalty for the extra stack. Stability is neutral on both, but the 2's taller-feeling, perched pod platform can read as slightly tippy at very slow paces (3/6), whereas the broader, planted Hyper base feels a touch more settled (4/6) — though neither offers pronation correction. Both share the same fast-effective window around 4:45–5:15 min/km and overlap on 10K and half-marathon duty, but the Hyper extends its range to the full marathon and protective long runs, while the 2 is happiest as a shorter, punchier uptempo trainer.
