Does a Carbon-Plated Shoe Actually Make YOU Faster?

Quick answer: On average, yes. Lab studies show carbon-plated racing shoes lower the energy cost of running by a few percent compared with conventional shoes. But the response varies a lot from person to person, and some runners get little or no benefit. The only way to know whether a carbon-plated shoe suits you is to look at your own data.

Walk into any running store in Singapore, and you'll see them: thick-soled, brightly coloured, carrying price tags that make you look twice. Carbon-plated shoes have gone from elite-only kit to something many everyday runners are asking about before a first 10K or half marathon.

The marketing makes it sound simple: put them on and run faster. The research tells a more interesting story. The average effect is real, but "average" is not the same as "you."

What Is a Carbon-Plated Shoe?

Most carbon-plated shoes combine a stiff, curved plate with a thick, springy midsole foam. Researchers group these designs under the term advanced footwear technology (AFT). The idea is to lower the energy your body needs to hold a given pace, which is the same quantity we describe in our guide to running economy: how much oxygen you use at a fixed speed.

Lower energy cost doesn't automatically mean a faster race. But if you can hold the same pace for less effort, you have more left in the tank for the final kilometres.

What the Research Says on Average

The headline numbers come from a handful of well-known lab studies:

• In a study of 18 high-caliber male runners, a Nike prototype racing shoe lowered the energetic cost of running by about 4% compared with two conventional marathon racing shoes. All 18 runners improved, with individual savings ranging from roughly 1.6% to 6.3%.
• A later randomised crossover study of 24 highly trained runners (12 men and 12 women) found the Nike Vaporfly improved running economy by 4.2% over a conventional marathon shoe, and by 2.6% over track spikes. When the Vaporfly was weight-matched to the conventional shoe, the improvement was still 2.9%, so shoe weight alone didn't explain the benefit.
• A 2023 analysis that combined new data with a meta-analysis found an overall medium-sized benefit of AFT on running economy compared with traditional racing flats.

But the Average Isn't You

Here's the part the marketing leaves out. The same 2023 study measured how much individual runners differed from one another. Among Kenyan world-class runners, responses ranged from an 11.3% drawback to an 11.4% benefit. Among European amateur runners, they ranged from a 9.7% benefit to a 1.1% drawback. The authors concluded that "a more personalized approach to shoe selection might be necessary for optimal benefit".

Even in the 24-runner crossover study, individual savings over a conventional marathon shoe varied across speeds from about 1.7% to 7.2%. That study also reported that changes in running economy were only trivially or weakly related to changes in the biomechanical variables measured, which means you can't reliably predict who will respond just by looking at their form.

The average effect is real, but 'average' is not the same as 'you.'

What About Slower Runners, and Hills?

Most early studies used fast runners at fast speeds, so a fair question is whether everyday runners benefit too.

A 2026 randomised crossover study of 14 moderately trained runners tested speeds from 7.5 to 12 km/h. The AFT shoe lowered oxygen cost by roughly 2.5% compared with the traditional shoe, and the benefit did not depend on speed. The authors also noted that comfort was a stronger driver of shoe preference than running economy. The sample was small and the testing was done on a treadmill, so it's encouraging evidence rather than a final answer.

Terrain matters too. In a study of 16 competitive male runners at 13 km/h, the savings in a plated shoe were 3.83% on level ground but smaller on slopes: 2.82% uphill and 2.70% downhill. If your usual routes include climbs and overhead bridges, the benefit you see on a flat course may not carry over in full.

Faster in the Lab Versus Faster on Race Day

Energy savings and finishing times are related, but not identical. Researchers have also examined how elite marathon performances changed alongside the arrival of these shoes, which tells us something about the elite end of the sport. For everyday runners, the better question is practical: does this specific shoe let me hold my target pace for less effort, and does it feel good over the full distance?

Injury Considerations

Any change in footwear changes how load travels through your body, and carbon-plated shoes are no exception. A 2023 case series described five runners, mostly elite, who developed navicular bone stress injuries while using carbon fibre plate footwear. The authors framed this as a possible association and were clear that the cause in each case could not be determined, noting factors such as prior navicular injury, orthotics, rapid training increases and faster running speeds.

The sensible takeaway is to treat a new pair of carbon-plated shoes like any other change to your training: introduce them gradually, pay attention to new pain in the midfoot, and speak to a clinician if something doesn't settle.

Carbon-Plated Isn't the Only Option: Consider Cushioned Shoes

A carbon-plated shoe is a racing tool. For many runners, especially on easy days, long runs, and in the early months of training, a well-cushioned everyday shoe may be the smarter choice. The research gives a few reasons to take that option seriously, along with a few reasons not to assume it's automatically better.

Cushioning can help running economy too. A systematic review and meta-analysis of footwear and running economy found a small economy benefit for cushioned shoes and a trivial one for shoes that runners found comfortable. The same review linked heavier shoes to a higher metabolic cost, although a combined shoe mass under 440 g per pair showed no detrimental effect. None of the included studies measured actual running performance.

Comfort and injury risk. In a 2025 analysis of 527 recreational runners followed for six months, runners who perceived their shoes as more cushioned had a lower risk of injury. The authors stress that causality can't be inferred, and that runners who were already injured may have rated their shoes more harshly. In a related randomised trial of 848 recreational runners, those given the firmer version of a shoe had a higher injury risk than those given the softer version.

But more cushioning isn't automatically gentler. In a small lab study of 12 male runners, a highly cushioned maximalist shoe produced higher leg stiffness and higher impact peaks than a conventional shoe, by about 6% at 10 km/h and 11% at 14.5 km/h. The authors concluded that such shoes "amplify rather than attenuate impact loading". With only 12 men and one model of each shoe, this can't be generalised, but it shows that "softer" doesn't always mean "easier on the body."

What this means for you. The evidence points in more than one direction, which is another reason individual response matters. Comfort also counts: in the slow-speed study above, comfort was a stronger driver of shoe preference than running economy. A common approach is to keep a carbon-plated shoe for races and key sessions and use a comfortable, cushioned shoe for easy and long runs. That is widespread practice, not a research-backed rule.

A good shoe recommendation should be open to the answer being 'not a carbon-plated shoe.'

Why Your Mechanics Decide the Answer

If the benefit differs so much from runner to runner, what determines whether it works for you? The honest answer is that research hasn't fully explained it, and the 24-runner study found only weak links to the biomechanical variables it tracked.

That is exactly why measuring your own running is more useful than copying a friend's shoe choice or trusting a rule of thumb.

At FORGED by ReFormd, our 3D Running Gait Analysis is paired with a shoe recommendation. Using the MotionMetrix G2, which combines a depth-sensing camera with a force-sensing treadmill, we assess your mechanics, energy use and loading patterns against normative data, then give individualised guidance on whether a carbon-plated shoe or something more stable is the better match for how you run.

MotionMetrix describes the G2 as a platform built for functional shoe fitting, with a treadmill-embedded force sensor capturing the force you apply.

Who Should Think About Carbon-Plated Shoes?

You don't need to be an elite athlete to ask the question, but the answer will look different depending on where you are in your running.

Worth testing if you:

• Are training consistently for a race and want to know whether a racing shoe suits your stride
• Have tried a carbon-plated pair and aren't sure whether it's helping or just feels different
• Are choosing between a carbon-plated racing shoe and a stability shoe and don't want to guess
• Are a hybrid or HYROX athlete who runs a lot of kilometres between stations

Worth taking more care if you:

• Are new to running and still building your base, where fit, comfort and gradual progression matter most
• Are returning from injury, especially in the foot or lower leg
• Have a history of bone stress injuries, in which case it's worth discussing with a clinician first

Frequently Asked Questions

Do carbon-plated shoes work for slower runners? Possibly. A recent crossover study at speeds of 7.5 to 12 km/h found an average benefit of around 2.5%, but it was a small study, and individual responses vary.

Are carbon-plated shoes bad for injuries? The evidence so far is limited to case reports, and the authors of the main case series say the cause can't be determined. Introduce them gradually and see a clinician if you develop new foot pain.

Do I need to train in them or just race in them? Research on how often to wear them is limited. Many runners and coaches reserve them for key sessions and race day while building up gradually, but this is common practice, not a research-backed rule.

Will a carbon-plated shoe make me faster by a set amount? No. Lab studies measure energy cost, which doesn't convert neatly into minutes, and individual results range from little benefit to large benefit.

Here’s a video on whether carbon-plated shoes are for YOU.

The Bottom Line

Carbon-plated shoes do lower the energy cost of running for most people tested, but "most" is not "all," and the size of the effect varies widely. Whether one will make you faster depends on your mechanics, your pace, your terrain and how your body adapts, and that is something you can measure instead of guess.
