New Balance FuelCell SuperComp Trainer 3

Ed's pick of the four super-trainers compared if he had to race — softer and more propulsive than the Superblast 2 or Deviate Nitro 3, more fun and natural-rocking than the Cielo X1 at faster paces. UK pricing is the only major knock. — EDDBUD

BP
Ben Parkes Youtube

A fantastic long-run cruiser that loses some of v2's pop in exchange for stability — recommended at the US $180 price, but the UK £230 pricing makes it nearly impossible for Ben to recommend over a Vaporfly 3 or Endorphin Pro at the same number.

Best for: Mid-pack runners training for half/full marathons who want a comfortable, dependable, plated long-run trainer over an all-out lightweight racer.

+1 earlier review from Ben Parkes

One of Ben's favourite shoes of the year — the most comfortable plated training/race shoe on the market for him; only knock is the price.

Best for: Mid-pack and back-of-pack marathoners who want comfort and a plate for long marathons; great entry-level carbon-plated shoe.

Doctors of Running Youtube

A more stable, stiffer, less-bouncy super trainer than v2 — better suited for uptempo training and marathon racing for average runners than for easy days, with great durability and improved guidance, but a finicky tapered toebox.

Best for: Uptempo runs, marathon-pace long runs, and a forgiving, durable marathon racer for runners who find the SC Elite v4 too aggressive.

A firmer, stiffer, more guided alternative to the Balos — better when you want plate-driven uptempo support and structure rather than a soft flexible cruiser.

Best for: Runners who want a stable, plated long-run/uptempo trainer with smooth rocker rather than a flexible, bouncier max-cushion cruiser.

v3 swings back toward training duty — firmer, more stable, more guided than v2's bouncy uptempo/racing personality; pick v3 if you want a stable plated trainer, v2 if you want a faster racy shoe.

Best for: A pure super-trainer for daily training and long runs, especially for runners with stiff toe joints who want a smooth rocker.

Ed's pick of the four super-trainers compared if he had to race — softer and more propulsive than the Superblast 2 or Deviate Nitro 3, more fun and natural-rocking than the Cielo X1 at faster paces. UK pricing is the only major knock.

Best for: Versatile long runs and racing for runners who want softness, plate, and durability over a fragile super-shoe.

+1 earlier review from EDDBUD

10.3/12 overall — well-built, smooth plated long-run trainer with a refined upper and good outsole; midsole is a strong balance, but the £229 UK price is hard to justify versus Puma Deviate Nitro 3, and the throwaway insole and a heel-rub spot keep it from being great.

Best for: Long-distance training and marathon running for masses-of-runners who want plate stability with a soft, wide platform — middle ground for runners who can't get on with very narrow racers like the Vaporfly.

K
Kofuzi Youtube

A comparable tall-stack daily trainer to the Hyperion Max 4 using PEBA-blend FuelCell and a full carbon plate; feels a bit dense and sluggish to Kofuzi but is popular with heavier runners seeking marathon support, and offers slightly more flexibility than the Max 4.

+1 earlier review from Kofuzi

A great long-run trainer and clear upgrade over v2 — Kofuzi loves the new geometry and that the rubber nubbin under the plate is gone, but feels v3 lost some of v1's quirky character and is a touch bland.

Best for: Long easy runs, progression long runs, and long runs with marathon-pace miles for runners who want a stable, plated trainer.

RM
Run Moore Youtube

The best of the SC Trainer lineage and the best $170-$190 plated high-cushion trainer Steve has run in — clean upper-fit, stable cruising rhythm once you warm up, and the strongest version of New Balance's good/better/best fuel-cell tiering this year.

Best for: Plated high-cushion trainer for daily training and long marathon training runs at steady cruising paces — best value in the $170-$190 plated trainer category for Steve.
