Hoka Mach X 3 Review
The Hoka Mach X 3 is a road running shoe designed to provide propulsion for a faster, more efficient gait. It shares some of the benefits of a carbon-plated racing shoe but is intended for up-tempo runs, fartlek sessions, intervals, and steady runs. As a performance trainer, it can be worn more regularly than a dedicated racing shoe.
Hoka has made several updates in version three of the Mach X, starting with the upper construction. The Mach X 2 had a very open mesh upper with minimal structure and a flimsy heel cup, which reduced weight but compromised snugness and comfort. The Mach X 3 upper, now more similar to that of the Mach 6, offers greater comfort—ideal for a shoe designed for frequent use. It remains a wrap-knit design that’s breathable but with smaller perforations, making it less drafty on cold mornings. With the Mach X 2, I often needed warm socks in winter; that’s no longer necessary.
The heel cup, while still flexible, now holds its shape better and includes light padding around the heel and collar for instant comfort without excess bulk. The tongue is padded at the top to protect from lace pressure but thinner further down, and it features a tab to keep it centred during runs. An additional top lace hole allows for a snugger heel fit or butterfly lacing. The fit is consistent with other Hoka models—narrower than many other brands. Compared to the Mach X 2, version 3 feels slightly narrower in the forefoot, particularly just behind the toe joints, offering a snugger overall fit. The straight big-toe line promotes a positive toe-off feel.
Stack height is 44mm in the heel and 39mm in the forefoot for men, and 38mm/33mm for women. The dual-density midsole pairs a PEBA top layer (soft, high rebound) with a Pebax propulsion plate, both sitting atop an EVA foam layer for stability. While the stack height and layout remain the same as the Mach X 2, the ride feels different. The Mach X 2 was extremely soft and bouncy, which made runs faster but required extra effort to engage the foam—almost like bouncing down the road. The Mach X 3, with slightly firmer EVA, delivers a smoother transition through the gait cycle. The rocker geometry feels more prominent, creating a sensation of rolling forward effortlessly rather than springing.
Cushioning remains soft and forgiving but with less bounce, making the Mach X 3 easier to run in—particularly at slower paces. It performs well across various sessions, from easy runs to track intervals and end-of-run strides. Propulsion comes from the PEBA foam’s rebound, the Pebax plate’s stiffness, and the midsole’s curved geometry. The 5mm drop encourages midfoot striking to reduce braking forces. Hoka’s “Speed Centric Meta-Rocker” design helps maintain quick cadence and upright posture, allowing runners to move efficiently with less effort than in a standard trainer.
Although the Mach X 3 rides differently from the Mach X 2, performance benefits remain similar—I was still a few minutes quicker on steady runs, with noticeably less leg fatigue. The added upper structure increases weight slightly, but it’s negligible: 243g for a women’s UK5 and 286g for a men’s UK8. On the run, they feel exceptionally light.
Despite the high stack height, it’s not particularly noticeable when standing or running, except on rough ground or sharp turns (these are road shoes, not for cross-field shortcuts). On the track, they perform seamlessly. Hoka’s sizing is similar to New Balance, Karhu, Inov-8, and La Sportiva. If you wear Brooks, Saucony, 361, Topo, or Altra, consider going half a UK size smaller (e.g., a UK 11 in Brooks equates to a UK 11.5 in Hoka).
In summary, the Hoka Mach X 3 is more versatile than its predecessor, capable of handling easy runs as well as tempo, steady, and interval sessions. Its cushioning and smooth, responsive ride make it suitable even for long runs over two hours, with enough energy return for late-run pickups.
Alternatives to Hoka Mach X 3
New Balance Fuelcell Rebel v5: The New Balance Rebel v5 has a soft more flexible ride than the Hoka Mach X 3. The rocker/curved shaped midsole gives some propulsion but, there isn’t a plate and the Peba foam is mixed with EVA which reduces the rebound. This makes it not quite as quick but, does allow more foot function and a more natural feel to the ride. Available in two width men’s and women’s. https://www.northernrunner.com/blog/new-balance-fuelcell-rebel-v5-review/
Brooks Hyperion v3: The Brooks Hyperion v3 has a nimbler feel than the Hoka Mach X 3. It has a similar soft responsive foam but, has a lower stack height, no propulsion plate and is more flexible. They lack the cushioning over the longer distances but are more fun to wear for shorter intervals. https://www.northernrunner.com/blog/brooks-hyperion-3-review/
Brooks Hyperion Max v3: The Brooks Hyperion Max 3 has a much softer ride than the Hoka Mach X 3. This makes it less versatile. It is nice on longer outings but, too soft for short efforts and track workouts. https://www.northernrunner.com/blog/brooks-hyperion-max-3-review/
Brooks Launch 11: The Brooks Launch is a light, nimble training shoe that offers a responsive midsole and fast feel. These aren’t as forgiving on longer runs but are fun to wear on shorter quicker runs. https://www.northernrunner.com/blog/brooks-launch-11-review/
Topo Athletic Specter 2: A broad rounded toe box gives the feet the space to spread and function inside the shoes. The midsole is made entirely from Peba but is firmer and more responsive than the foam used for the top part of the Hoka Mach X 3 midsole. Despite the lack of a propulsion plate these are a fast shoe that can be used for long races or training runs as well as shorter efforts too. https://www.northernrunner.com/blog/topo-athletic-specter-2-review/
