An early but strongly positive verdict: a stable, firmer-riding plateless long-run super trainer that has cleared his 10-12 mile litmus test and will replace the Superblast 3 for his marathon-block long runs, with the coarse warm upper and the steep 210 GBP price as the main knocks. — FORDY RUNS
A solid, stable, smooth-riding long-run cruiser that gets outclassed at its $220 price by the Superblast 3 and Hyperboost Edge — and by its own LightSpray sibling.
Best for: A long-run cruiser for easy-to-moderate paces, ideal for 10+ mile runs where you want to lock into a rhythm.
His fifth pick: a big upgrade over the previous Cloudmonster Hyper that handles long runs and intervals well and is durable, held back only by being the most expensive shoe in the lineup.
Best for: Runners wanting a versatile super trainer for long runs and intervals who don't mind the high price
A much-improved super trainer over the original Cloudmonster Hyper, with full-length PEBA transforming the ride into a genuinely fast, versatile option.
Best for: Steady runs, tempo work, and long runs with pickups — a true super trainer.
A comfortable, easier-effort marathon option for less aggressive runners, but not in the same performance category as a true race shoe like the Specter Elite.
Best for: Comfortable, less aggressive marathon efforts for recreational runners rather than fast racing.
One of Doctors of Running's favorite performance trainers of 2026 — a bouncy, wide, and inherently stable shoe that handles everything from easy miles to workouts without issue.
Best for: Runners with medial stability needs who still want a versatile shoe for easy miles, long runs, tempo, and even track intervals.
The consensus pick for daily trainer of the year so far, praised by multiple testers for its fit, stability, and durability (100+ miles with no outsole wear).
Best for: Daily mileage for neutral runners who also want some pop for strides or pickups.
David's #2 all-time max cushion pick — the Cloudmonster 3 Hyper encapsulates premium Helion HF foam in a stable, well-beveled platform that delivers excellent cushioning and guidance without instability, though it tops out at a lower pace ceiling than the Megablast.
Universally loved across the DoR team — best balance of any super-trainer this year for daily training through marathon racing, with excellent durability.
Best for: Versatile do-it-all daily trainer that can also serve as a marathon-racing alternative for runners who don't gel with aggressive super shoes
Picked as the most-stable and most-versatile of the three super trainers, with the snappiest ride and best durability — the reviewer's overall favorite of the group.
Best for: Versatile super trainer that can handle daily training through faster tempo work — best balance of stability, snap, and durability
Surprisingly stable-neutral with very high sidewalls and a tall medial arch — Matt has done long runs and workouts in it without issue. Firmer and snappier than the Endorphin Azura and his pick for runners wanting more obvious medial structure.
Best for: Heavier or pronation-prone runners who want a firmer, snappier max-cushion daily trainer with high sidewalls and a tall medial arch
Both David and Andrea rank it among their favorites of 2026 so far — a stable-neutral long-run and daily trainer with a nice heel bevel, forefoot rocker, and excellent lockdown that pairs well with the Lightspray variant.
The Cloudmonster 3 Hyper is a significant improvement over version 2 with a better upper and more refined stable neutral ride powered by Helion HF, making it a capable workhorse daily trainer, though the anticipated $220-250 price may be steep for performance offered.
Best for: Stable neutral daily training and long runs for runners who want a firmer high-stack shoe
Dave sees the Cloudmonster 3 Hyper as the pick for a pure running experience in the lineup, offering a lighter, springier ride than the standard Cloudmonster 3 while keeping a structured, rockered feel.
Best for: A pure running-focused structured daily trainer for runners who like a firmer super-foam ride with an aggressive rocker.
A surprise long-run favourite for Fordy: he expected to dislike the Pebax/EVA CloudTec combo but has ended up preferring it over the Superblast for longer runs, and it's locked into his marathon block rotation.
FORDY RUNS' On pick despite normally being skeptical of the brand; praised for its PEBA foam in CloudTec frame as a brilliant shoe he really loves.
An early but strongly positive verdict: a stable, firmer-riding plateless long-run super trainer that has cleared his 10-12 mile litmus test and will replace the Superblast 3 for his marathon-block long runs, with the coarse warm upper and the steep 210 GBP price as the main knocks.
Best for: Long runs and marathon-training miles at easy to steady paces, especially for runners who find the Superblast 3 too soft
Kofuzi calls it the best of the three Cloudmonster 3 models and an excellent grand-touring long run/daily trainer that is soft yet still snappy, though slightly heavy and lacking pop for true marathon-effort work.
Best for: Long runs and comfortable daily training, including long runs with some uptempo pickups
The Cloudmonster 3 Hyper LS is described as one of the best shoes one reviewer has tried this year, up there with the Megablast, with great comfort and outsole. It advances via coin toss but is ultimately eliminated.
A comfortable, good-looking accomplished cruiser for easy miles, but it lacks firepower and feels like a standard daily trainer priced like a super trainer.
Best for: Easy to mid-pace cruising miles and a good-looking crossover shoe
The Cloudmonster 3 Hyper is an improved cruiser over its predecessor but functions more like a comfortable daily trainer than a super trainer, and at $220 it struggles to justify its price versus lighter, more versatile alternatives.
Best for: Easy and long daily training runs for runners who want a stable, comfortable cushioned shoe without needing super trainer speed.
A standout daily trainer with dual-density foam giving both cushion and snap; the host's controversial pick for trainer of the year.
Best for: Plush daily training with snappy ride; also Tom's overall trainer-of-the-year pick
Reviewers note: Runs true to size in UK 8.5/US 9; secure midfoot lockdown with ample toe-box volume; gusseted tongue and padded heel collar prevent slipping.
