Road Racing

On Cloudboom Strike

A bouncy, propulsive super-shoe that excels from 10K to marathon for neutral runners, though reviewers split on whether its responsive ride and narrow heel suit longer distances or warrant the $280 price tag against comparable alternatives.

Doctors of Running Youtube ↑

On's best super shoe yet — bouncy, durable, well-balanced for 10K-marathon racing; competes with Alphafly and Endorphin Elite 2 in the upper echelon, though the narrow heel limits it for runners who fatigue on stability at longer distances.

Best for: Half-marathon to marathon racing for neutral runners with stable mechanics who want a bouncy, propulsive super shoe.

A softer, more controlled carbon racer with a gradual transition and a surprisingly cushioned forefoot, particularly well-suited to rhythmic half marathon and marathon efforts.

Best for: Controlled uptempo efforts at half marathon and marathon pace where the soft, rhythmic ride and forefoot cushion shine

source

A unique race shoe that uses the insert itself to shape the plate profile, giving a firm but propulsive ride; worked well for a 10K race and feels capable up to half marathon.

Best for: Race distances from 10K to half marathon for neutral runners who like a firm, propulsive feel

EDDBUD Youtube ↑

An enjoyable, softer super-shoe that's slightly more stable than the Adios Pro 4, but it's $40 more expensive, harder to find, and has a messier upper — so EDDBUD picks the Adios Pro 4 over it.

Best for: Runners wanting a softer, slightly more stable super-shoe ride with more forefoot cushion

+3 earlier reviews from EDDBUD

Ed's #10 of 2024 — exhilarating and fun, one of his most enjoyable shoes of the year.

Best for: Experienced plated-shoe users who like a midfoot/forefoot strike.

source

Easily the best On shoe EDDBUD has tried — bouncy, fun, range-of-pace super shoe scoring 11.4/12; rivals Metaspeed Sky Paris and Adizero Prime X Strung at the top of the racing category, held back only by overpriced retail (PS260) and durability concerns on the lateral heel rubber.

Best for: Midfoot/forefoot strikers wanting a bouncy, range-of-pace super shoe for everything from 5K up to marathon, especially fans of the ASICS Metaspeed Sky Paris ride.

15 miles tested · source

A narrower, firmer option with durability concerns around the heel — better reserved for 5K racing than all-round distance use.

Kofuzi Youtube →

A 10K-to-half marathon racer rather than a true marathon super shoe in Kofuzi's view; very responsive but lacks the dynamic cushion he wants for sustained marathon efforts, and at $280 feels overpriced versus Metaspeed Edge Paris and Adios Pro 3.

Best for: Efficient runners targeting 10K to half-marathon races who want more cushion than the Cloudboom Echo 3 but don't need a soft Alphafly-style ride.
