On Cloudmonster Void: 30 mm heel stack, 6 mm drop, 289 g — specs from independent lab testing.
Built for daily, long run, at a target pace of 7:30–10:00 /mi on road.
The midsole is Helion, tuned firm (2/5 on our cushioning scale). Energy return is moderate — comfortable and predictable rather than bouncy. 30 mm of heel stack keeps you low and connected, with more ground feel than most current trainers. Combined, the ride reads as snappy at 4/5 responsiveness.
A nylon (or PEBA-blend) plate adds structure without the harsh stiffness of carbon. You get a firmer, more propulsive toe-off that still flexes at slower paces, which is why nylon-plated shoes double as workout and long-run shoes rather than race-day-only tools.
A 6 mm drop is the mainstream middle — familiar to almost anyone coming from a standard trainer. The rocker is aggressive: the sole is curved and stiff enough to tip you into the next stride on its own, which saves the calf on long runs but feels strange when you slow right down. The forefoot flexes easily, so the shoe adapts to slower, shorter strides. It is a neutral platform with no built-in correction.
The toe-box is standard width — comfortable for most feet without swimming. It fits true to size. Expect roughly 400 miles from the outsole, about $0.45 per mile at $180.
