HOKA Mach X 3 Review & Sizing Guide

Published Updated

Buy Mach X 3 as a softer, more cushioned plated daily trainer if you never owned the Mach X 2; skip it if you prized the X2 ride and want the lighter, snappier feel — owners who loved v2 are stockpiling backup X2s before they vanish I now have two backup pairs because after trying the new x3, they definitely made the shoe much more tame.

Full breakdown

HOKA Mach X 3 is the third-generation plated daily/tempo trainer with a Pebax-based supercritical midsole and a PEBA-blend underfoot. Owners who loved the Mach X 2 are split on the v3 redesign, with a long-term Mach X 2 owner saying the v3 made the shoe more plush, heavier, and tamer they neutered this shoe in the 3rd version by making it more plush and also WAY heavier. Buy it as a comfortable plated daily for steady tempo runs, not as a true uptempo speed shoe.

FAQ

How does Mach X 3 compare to the beloved Mach X 2?

Worse, by long-term v2 owners' accounts — Mach X 3 is plusher but heavier and less lively. A 35-year-old reviewer with 150 miles on his Mach X 2 said it remains his favorite midsole and that the v3 update made the shoe much tamer, prompting him to stockpile two backup Mach X 2 pairs I am so bummed that they neutered this shoe in the 3rd version by making it more plush and also WAY heavier. If you have not run the X2, buy the X3 as a soft plated daily — but skip the upgrade if you came from the X2 and choose backup X2 stock instead.

Is Mach X 3 worth $200 over a cheaper unplated trainer?

Only if you specifically want the plated rocker ride for tempo days. The Megablast reviewer found Mach X 3 sits between novablast 5, mach 6 and glycerin max in feel — solid but muted like a higher stack amalgamation of the novablast 5, mach 6 and glycerin max. If you already own a great unplated daily trainer, the Mach X 3 mostly duplicates that slot at higher cost; skip retail and wait for $130-150 sale pricing.

Who is Mach X 3 actually best for?

Runners who want one shoe that covers daily, long-run, and tempo work and care more about cushion than racy bounce. The Hoka Rocket X 3 reviewer kept Mach X 2 as his work-horse for speed sessions while reaching for the Rocket for race-pace Mach X 3, new official pictures; the X3 plays the same daily-cushion role for runners new to the line. Buy it as a comfortable daily-plus-tempo workhorse, not as the GOAT do-it-all.
