Our verdict
Fixed heel, same snap, more weight.
The Mach X 3 is a high-stack neutral super trainer with a PEBA top layer, a firmer EVA base and a Pebax plate, built for tempo work and long runs at a purposeful pace. It suits neutral runners with a normal to narrow foot who land mid-foot or further forward, more than wide feet, heavy heel strikers or anyone after a soft recovery shoe.
Strong points
- New upper and padded collar fix the Mach X 2 heel rub
- One of the best rocker profiles Doctors of Running’s physio has felt
- Lively forefoot: 69.3 percent energy return in RunRepeat’s lab
- Deep cushioning, with 39 mm under the forefoot
- Versatile from easy days to tempo work and long runs
- Better wet grip than the X 2 and little outsole wear in the lab
Weak points
- Heavier than the X 2: 264 g against 247 g in RunRepeat’s lab
- Narrow, tapered toe box that limits toe splay
- Tongue without gusset that can fold or shift
- Flat heel: 58.9 percent energy return in RunRepeat’s lab
- Firm for easy runs according to some testers
Who it fits
- You want one plated shoe for tempo and long runs
- Your foot is normal to narrow
- You land mid-foot or further forward
- The Mach X 2 rubbed your heel
Who should skip it
- Your feet are wide
- You land hard on your heel
- You want a soft recovery shoe

How it feels
Written from 8 published tests. We quote measurements, not impressions we did not have.
Deep, with a firm edge. PEBA over firmer EVA and a Pebax plate, 44 / 39 mm: soft at first touch, firm and snappy once moving, per RunRepeat, RTINGS and Fleet Feet.
Steady for its height. Neutral but steady for its height thanks to a flared base and mild sidewalls; RTINGS scores stability 6.1, and steep descents call for care.
Springy forefoot, flat heel. Forefoot energy return of 69.3 percent against 58.9 at the heel in RunRepeat’s lab, with a rocker that rewards a mid-foot landing.
Deep, with a firm edge. A soft PEBA layer sits over a firmer supercritical EVA base, split by a Pebax plate. Fleet Feet lists 44 mm at the heel and 39 mm at the forefoot, and only 8 of the 181 neutral road shoes with a listed forefoot stack in our catalogue sit higher under the forefoot.
RunRepeat measured the foam at 32.5 AC, softer than average, and RTINGS rates the cushioning 8.7 out of 10. On the run, testers describe a soft first touch that turns firm and snappy: Fleet Feet found it firmer than ideal for easy runs, and one Doctors of Running tester felt it lean firm despite the stack.
Steady for its height. Doctors of Running call it a neutral shoe, steadied by a flared forefoot and mild sidewalls that intrude less than on older Hokas. The Run Testers found it fairly stable for a high-stack super trainer, and RunRepeat describes the plate mainly as a stabiliser.
The limits come from the height and the soft top foam. RTINGS scores stability 6.1 out of 10, and Doctors of Running advise care on steep descents, where the shoe tips you forward.
Springy forefoot, flat heel. RunRepeat measured 69.3 percent energy return at the forefoot, above average, but only 58.9 percent at the heel, where the EVA dulls the bounce. RTINGS found the same split, with a much springier forefoot than heel.
The rocker does much of the work. Doctors of Running’s physio rates it among the best rocker profiles he has run in on a super trainer, though the shoe is mid-to-forefoot oriented and heel strikers may find the transition awkward. RunRepeat measured the drop at 9.5 mm against 5 mm listed, RTINGS at 7.6 mm.

What the tests say
Published tests agree the Mach X 3 fixes the Mach X 2 heel, keeps its plated ride and puts on weight. They split on the room up front, on how firm it feels and on whether it beats the X 2.
| Test | Type | Our reading | In one sentence | Source |
|---|---|---|---|---|
| RunRepeat | Lab | Positive | RunRepeat scores it 83 out of 100: a good super trainer, best for narrow feet, held back by the tongue, the weight and a tight toe box. | Read |
| Doctors of Running | Review | Positive | Doctors of Running grade it in the A range: a versatile plated trainer from easy to uptempo paces, also a fit for finishing a marathon. | Read |
| Believe in the Run | Review | Mixed | Believe in the Run places it in its B tier: one tester calls it among the year’s best super trainers, another a missed opportunity. | Read |
| RTINGS | Lab | Mixed | RTINGS gives 7.4 out of 10: excellent cushioning and a springy forefoot, but heavy for a super trainer. | Read |

They agree
- The heel is fixedRunRepeat, Believe in the Run, Fleet Feet and The Run Testers all report that the reworked collar ends the heel rubbing of the X 2.
- Heavier than beforeRunRepeat weighed 264 g against 247 g for the X 2, The Run Testers found about 20 g more, and a Believe in the Run tester felt it lost some pep.
- Made for tempo and long runsBelieve in the Run, RTINGS, Doctors of Running and Fleet Feet all see it at its best at moderate to brisk paces over longer distances.
- True to lengthDoctors of Running, Believe in the Run, RTINGS and The Run Testers all ran in their usual size.
They split
- Roomy or narrow up front?RunRepeat measured a tapered 70.8 mm toe box and RTINGS a very narrow arch area. Believe in the Run and Doctors of Running found the toe box roomier than expected.
- Soft or firm?RunRepeat measured a soft 32.5 AC foam and RTINGS rates the cushioning highly, while Fleet Feet and one Doctors of Running tester found the ride leaning firm.
- Better than the X 2?RunRepeat calls it a solid step forward. One Believe in the Run tester and one of The Run Testers found it less snappy than the X 2 because of the extra weight.

Dashed: insole, hidden. Sources: Fleet Feet, RunRepeat, Believe in the Run, RTINGS, Doctors of Running, Running Warehouse, Runnea, Carreras de Montaña.
Upper. A new warp-knit upper replaces the Mach X 2’s mesh, softer and quick to break in according to Fleet Feet and Believe in the Run. RunRepeat rates breathability 3 out of 5, close to average.
Tongue. No gusset, and padded only where the laces press: 6.4 mm thick in RunRepeat’s lab. Believe in the Run found it flimsy below the laces and prone to folding.
Heel. The counter is reworked with extra foam and Hoka’s extended collar returns, flared away from the Achilles. RunRepeat rates the counter flexible, 2 out of 5, and Doctors of Running had no heel slip.
Midsole. A PEBA top layer over a supercritical EVA base, measured at 32.5 AC by RunRepeat. The platform is very rigid in torsion: 20.4 Nm against a 14.4 Nm average.
Plate. A winged Pebax plate between the two foams, same design as on the X 2. RunRepeat sees it mainly as a stabiliser with mild propulsion, Doctors of Running found it quite stiff, and Runnea points out that it is not carbon.
Insole. Removable and 5.0 mm thick. Doctors of Running found that average aftermarket insoles fit, thick ones less so.
Outsole. Rubber on the main wear zones only, 2.5 mm thick. Wet grip rose from 0.50 to 0.58 against the X 2 in RunRepeat’s test, and Doctors of Running note that the deep heel groove can trap stones.

Sizing and fit
Take your usual length; the real question is width, not size.

True to size
Widths
standard and wide
Toe room
Toe room is the weak spot. RunRepeat measured a 70.8 mm toe box against a 73.2 mm average, with good height at 28.5 mm, while Believe in the Run and Doctors of Running found the front roomier than expected.

Full sizing notes from testers
Doctors of Running, Believe in the Run, RTINGS and The Run Testers all ran in their usual size. RunRepeat’s owner poll leans slightly small, probably a reflection of the snug fit more than of the length.
The fit is narrow and close. RunRepeat measured a tapered toe box and RTINGS a very narrow arch area; Doctors of Running found the midfoot snug at first, easing within a few minutes. The tongue has no gusset, which RTINGS says can cost lockdown on narrow feet.
Widths: RunRepeat and Fleet Feet list a wide version, while Running Warehouse and RTINGS show only the standard D width. Check what your country offers.

Version history: Mach X 2 to Mach X 3
Warp-knit upper. It replaces the X 2’s mesh, and testers find the step-in much easier. (Believe in the Run, Fleet Feet)
Reworked heel. Extra foam in the counter and an extended collar end the rubbing that marked the X 2. (RunRepeat, Fleet Feet, The Run Testers)
Heavier. RunRepeat weighed 264 g against 247 g for the X 2; The Run Testers found about 20 g more in a UK 9. (RunRepeat, The Run Testers)
Better wet grip. Same outsole design, but RunRepeat measured wet traction up from 0.50 to 0.58. (RunRepeat)
Same midsole and plate. PEBA over EVA with the Pebax plate, unchanged according to Believe in the Run and Fleet Feet. (Believe in the Run, Fleet Feet)

Questions runners ask
Is the Hoka Mach X 3 true to size?
Yes for length. Doctors of Running, Believe in the Run, RTINGS and The Run Testers all ran in their usual size. The fit is narrow, though: RunRepeat measured a tapered 70.8 mm toe box and its owner poll leans slightly small, so wide or high-volume feet should try the wide version or a roomier shoe.
Mach X 2 or Mach X 3: which should I choose?
The Mach X 3 keeps the Mach X 2 midsole and Pebax plate, and adds a warp-knit upper and a padded heel collar that ends the X 2’s heel rubbing. It is heavier, 264 g against 247 g in RunRepeat’s lab. If the X 2 fit you well, it stays the lighter, snappier option.
Does the Hoka Mach X 3 have a carbon plate?
No. The Mach X 3 uses a winged Pebax plate, which flexes more than carbon, set between a PEBA top layer and a supercritical EVA base. RunRepeat sees it mainly as a stabiliser with mild propulsion, and Runnea finds it easier to get used to than a carbon plate.
How much does the Hoka Mach X 3 weigh?
About 266 g for a men’s US 9, the figure Running Warehouse lists. RTINGS weighed 267.6 g in that size and RunRepeat 264 g. The 288 g quoted elsewhere matches a larger size: Carreras de Montaña give 288 g for an EU 44. Either way, the Mach X 3 is about 17 g heavier than the Mach X 2 in RunRepeat’s lab.
Is the Hoka Mach X 3 good for a marathon?
As a training and finishing shoe, yes. Doctors of Running see the Mach X 3 as a tool to complete a marathon, and RTINGS scores it 7.4 for marathon racing. For a time goal, Fleet Feet would choose a lighter racer such as the Rocket X 3, and Runnea advises some experience with reactive shoes before racing long in it.
Is the Hoka Mach X 3 good for wide feet?
Usually not in the standard width. RunRepeat advises medium and wide feet to look elsewhere because of the tapered toe box, and RTINGS found a very narrow arch area. RunRepeat and Fleet Feet list a wide version, but Running Warehouse only shows the D width, so availability varies by country.
Can I use the Hoka Mach X 3 for easy runs?
Yes, with a caveat. Believe in the Run and The Run Testers enjoyed the Mach X 3 on easy days, but Fleet Feet found it firmer than ideal at slow paces and RTINGS found it more comfortable at moderate to fast paces. It makes most sense as the shoe for tempo and long runs, next to a softer trainer for recovery.
