Super Shoes For Running: How They Work And Do They Make You Faster?
Super shoes have changed distance running. Once seen mainly on the feet of elite marathon runners, they are now a familiar sight at local 5Ks, parkruns, half marathons and marathons around the world. Their distinctive combination of lightweight construction, deep responsive cushioning and stiffening technology is designed to help runners use less energy and potentially race faster.
That promise comes at a price. Many of the leading super shoes cost more than £200 or $250, which is a considerable investment for shoes you may mainly use on race day. So what makes a running shoe a super shoe, how much difference can the technology make and do you need to be a fast runner to benefit?
What Are Super Shoes?
Super shoes are performance running shoes designed to improve running economy and help runners get more from the fitness they have developed in training. You may also see them described as carbon plated running shoes or, particularly in scientific research, advanced footwear technology.
There is no single specification that makes a running shoe a super shoe. Most combine a very lightweight and responsive midsole foam with a relatively high stack of cushioning, a stiffening structure and carefully designed shoe geometry. Carbon fibre plates are common, but manufacturers have developed different systems, including carbon rods and alternative plate configurations.
The shape of the shoe is another important part of the design. Many super shoes use a pronounced rocker that helps you move through your stride, particularly as you transition towards toe off. The performance of a super shoe therefore comes from the complete package rather than simply putting a carbon plate inside a conventional running shoe.
How Do Super Shoes Work?
Every time you run, your body uses energy to move you forward. One of the main aims of a super shoe is to reduce the amount of energy you need to maintain a particular pace, something researchers measure through running economy.
The advanced foams used in modern racing shoes compress when your foot hits the ground and return some of that energy as they rebound. A plate or other stiffening structure works alongside the foam, while the shape of the midsole influences the way the shoe moves from landing towards toe off. Manufacturers also try to keep the overall weight low despite providing a large amount of cushioning beneath the foot.
It is the interaction between these different elements that matters. The carbon plate receives much of the attention, but the plate alone does not explain the performance benefits associated with modern super shoes. This is also why two carbon plated running shoes can feel completely different even when their specifications initially appear similar.
Do Super Shoes Actually Make You Faster?
There is substantial evidence that advanced running shoes can improve running economy. Put simply, you may be able to maintain a particular pace while using less energy than you would in a more traditional running shoe.
That does not mean every runner will experience the same improvement. Studies consistently show that individual responses vary, with the size of the benefit depending on the runner and the particular shoes being compared.
An improvement in running economy should not be confused with an identical improvement in race time either. Your performance still depends on your fitness, pacing, fuelling, course, weather and numerous other factors. Super shoes can potentially give you an advantage, but they cannot tell us exactly how much faster you will run.
For runners chasing personal bests, even a relatively small improvement can still be valuable. After months of training to become faster, footwear is one of the final areas where you may be able to gain a little more performance.
How Much Faster Can Super Shoes Make You?
There is no reliable calculation that will tell you exactly how many seconds or minutes a particular super shoe will save. Laboratory studies can measure changes in running economy, but translating those results into an individual race result is much more complicated.
Your running style, speed and biomechanics may interact particularly well with one shoe and less effectively with another. A shoe that produces excellent laboratory results or has been used to break world records is not automatically the shoe that will produce the greatest benefit for you.
Comfort and feel therefore remain important when choosing a super shoe. You still need a shoe that fits properly, feels sufficiently stable and works well at the pace you intend to race.
Do Super Shoes Work For Slower Runners?
One of the biggest questions surrounding super shoes is whether you need to be fast enough to make the technology work. Much of the early research involved relatively quick runners, which created understandable uncertainty about whether the same benefits would apply further back in the field.
More recent research has provided encouraging evidence at slower running speeds. Studies involving recreational runners have found improvements in running economy from advanced footwear technology at speeds much closer to those used by everyday runners, including paces considerably slower than those normally associated with elite racing.
That does not mean every recreational runner will receive the same advantage, but it challenges the idea that super shoes only begin to work once you reach elite speeds. Someone chasing a 30 minute 5K, two hour half marathon or five hour marathon may still benefit from the technology if they find a shoe that works well for them.
The decision is therefore less about whether you are fast enough for super shoes and more about your goals, budget and whether you actually enjoy running in them.
Super Shoes And Carbon Plated Running Shoes
Super shoes and carbon plated running shoes are often treated as the same thing, but there is an important difference. A carbon plated running shoe is simply a shoe containing a carbon fibre plate, while a super shoe relies on the interaction between several design features.
Modern super shoes combine their stiffening system with responsive foam, low weight and carefully designed geometry. Adding a carbon plate to an otherwise conventional running shoe does not automatically create the same performance characteristics.
This distinction has become increasingly relevant as manufacturers experiment with different designs. Carbon fibre remains common, but it is better to consider the complete shoe rather than judging its performance credentials solely by the presence of a carbon plate.
Which Brands Make Super Shoes?
Almost every major running shoe company now has a high performance racing range. Nike helped start the modern super shoe era with the Vaporfly and later the Alphafly, but the days when Nike had this part of the market largely to itself are long gone.
Adidas has its Adizero Adios Pro family, while Asics offers the Metaspeed range. Saucony has developed the Endorphin Pro and Endorphin Elite, New Balance has its FuelCell SuperComp Elite, and Hoka has the Rocket X range. Puma, On, Mizuno and a growing number of Chinese running shoe brands also compete in this area.
The choice can be overwhelming because these shoes do not all feel alike. Some provide a particularly soft and bouncy ride, while others feel firmer and more aggressive. Some have a broader platform that can feel relatively stable, while others prioritise low weight and a more stripped-back racing experience.
There is no single best super shoe for every runner. The growing choice is useful because you now have a much better chance of finding a model that suits the way you run than when only a handful of serious options were available.
Which Race Distances Are Super Shoes For?
Super shoes are closely associated with the marathon, but they are not limited to 26.2 miles. Many models are designed to be raced over distances from 5K through to the marathon, although the characteristics you prefer may change with the distance.
For a 5K or 10K, you might prefer a lighter and more aggressive shoe that feels particularly responsive when running quickly. Over a half marathon or marathon, cushioning, comfort and how the shoe feels as you become tired may become more important.
That is another reason not to assume that one racing shoe will be perfect for every runner and every distance. The super shoe you enjoy for a fast 5K may not necessarily be the shoe you want to wear for several hours in a marathon.
Should You Use Super Shoes In Training?
Racing is where super shoes make the most obvious sense, but you can also use them in training. Many runners keep them for races and selected faster sessions, which gives them an opportunity to become familiar with the shoes without putting all of their weekly mileage through an expensive pair.
Race pace sessions are particularly useful because they allow you to find out how the shoes feel at your intended pace, whether you experience any rubbing or pressure points and whether they remain comfortable and stable as the run gets longer. Race day should not be the first time you run in a new pair.
There is little reason for most runners to wear their race shoes for every easy run. Everyday running shoes are generally a more economical choice for regular mileage, while a growing category of super trainers offers some of the responsive foams, plates and geometry associated with racing shoes in a package designed for more frequent training.
How Long Do Super Shoes Last?
There is no fixed mileage at which a super shoe suddenly stops performing. Durability varies according to the shoe, your weight and running style, the surfaces you run on and how frequently you use it.
It is also useful to distinguish between the overall life of the shoe and its peak racing life. The outsole and upper may still be in perfectly usable condition even when the midsole no longer feels quite as responsive as it did when the shoe was new.
For that reason, some runners eventually move an older pair of super shoes from racing into faster training. Reserving a newer pair for a small number of key sessions and races can also help you get more racing use from an expensive purchase.
Why Are Super Shoes So Expensive?
Super shoes sit at the premium end of the running shoe market because they use specialist materials and require considerable development. Lightweight responsive foams, complex stiffening systems and the challenge of combining a large amount of cushioning with very little weight all contribute to the cost.
There is also intense competition between running shoe manufacturers. Brands invest heavily in materials, biomechanics, athlete testing and prototypes in pursuit of relatively small performance improvements, and flagship racing shoes are priced accordingly.
Whether that represents good value is much more personal. Spending more than £200 on shoes to gain a potentially small advantage will make little sense to some runners, while someone who has spent months preparing for a marathon personal best may look at the same purchase very differently.
Are Super Shoes Worth It?
If your main priority is simply enjoying your running, you certainly do not need super shoes. Conventional running shoes can be perfectly suitable for racing, and spending more money does not automatically give you a better running experience.
The calculation changes when performance becomes important. If you have spent months improving your training, nutrition, pacing and recovery in pursuit of a personal best, choosing footwear that may improve your running economy becomes a reasonable part of your race preparation.
That still does not make every super shoe good value for every runner. Fit and comfort remain fundamental, and an expensive racing shoe that feels uncomfortable or unstable is unlikely to be a sensible purchase simply because its technology has performed well in laboratory testing.
Are There Any Downsides To Super Shoes?
Cost is the most obvious disadvantage, particularly if you already own perfectly good running shoes. Super shoes can also feel very different from conventional shoes, and the combination of a high stack and aggressive geometry will not suit everyone.
Stability can be another consideration. Some high-stack racing shoes can feel less secure around tight corners or on uneven surfaces, although there are considerable differences between models. Racing shoes may also have a less forgiving fit because low weight and performance have been prioritised over the versatility expected from an everyday shoe.
There is also no guarantee that you will receive the same benefit as another runner.
Research describes average responses across groups as well as considerable individual variation, which is another reason to choose your racing shoes according to how they work for you rather than simply following what the fastest runners are wearing.
Do Super Shoes Reduce Fatigue?
Many runners say their legs feel fresher during or after racing in highly cushioned super shoes. There is some evidence that advanced footwear can reduce physiological demands during prolonged running, but that is not the same as proving that super shoes reduce muscle damage or improve post-race recovery.
Advanced footwear can also alter running mechanics and change how work is distributed through the body. Research involving recreational runners has found running-economy benefits without systematic increases across several biomechanical measures that have been discussed in relation to injury risk, but that does not establish that super shoes prevent injuries or are safer for every runner.
The evidence for improved running economy is much clearer than the evidence for improved recovery or reduced injury risk. If your legs consistently feel better after racing in a particular shoe, that may still be a useful factor in your own decision.
Can You Race In Super Shoes?
Most mainstream super shoes are designed specifically for competition, but shoes used in events governed by World Athletics rules have to comply with its footwear regulations. For road running events, the current maximum permitted sole thickness is 40mm.
Different rules apply to track competition, where the current maximum sole thickness is 20mm for track events. World Athletics also operates an approval system for competition shoes, so runners competing where these regulations apply should check that their particular model is permitted.
For the majority of recreational road runners, buying a mainstream current road racing model is unlikely to create a problem. If you are unsure about a particular shoe or competing at a level where footwear regulations are being enforced, checking the current World Athletics approved shoe list is sensible.
Do You Need Super Shoes To Run A Personal Best?
Super shoes can provide an advantage, but they remain a small part of the much bigger performance picture. Consistent training, appropriate mileage, recovery, sensible pacing and good race day nutrition will have a far greater influence on what you achieve.
Runners were setting personal bests long before modern super shoes appeared, and there is no reason you cannot continue to do so in conventional running shoes. A super shoe cannot create fitness that you have not developed or rescue a race undermined by poor preparation.
It is better to think of the technology as a way of potentially getting a little more from the fitness you already have. If you have done the training and are chasing every reasonable improvement on race day, that small advantage may be valuable.
Final Thoughts On Super Shoes For Running
Super shoes are neither an expensive gimmick nor a shortcut to faster running. The evidence shows that advanced footwear technology can improve running economy, and more recent research indicates that those benefits are not restricted to elite running speeds. Recreational runners can benefit too, although the size of the advantage varies between individuals and shoes.
Whether that makes them worth buying is a different question. If you are happy with your running and have no interest in spending more than £200 on racing shoes, you do not need them. Conventional running shoes remain perfectly capable of taking you through training and across a finish line.
If you have trained hard for a race, are chasing a personal best and want to give yourself every reasonable advantage, the calculation changes. Finding a super shoe that fits well, feels good at your race pace and works with the way you run could help you get a little more from all the work you have already done.
