Super trainers are fast, fun, and maybe a little risky. Here’s what to know about these max-cushioned shoes. 

Banned shoes emerged courtside long before they found their way onto a marathon course. Legend has it that nearly 40 years ago, Michael Jordan laced up a pair of red-and-black high-tops in violation of the NBA’s approved uniform colors. 

In 2010, the league cracked down again—this time, for reasons besides aesthetics—on a pair of basketball shoes that were shown to increase a player’s vertical-jump height. Today, Nike’s Air Jordan brand is a household name and multibillion-dollar business, and shoemaker Athletic Propulsion Labs (APL) has since released additional banned styles (Superfuture and Concept X) of its performance-boosting kicks.

Though some speculate these bans were mostly crafty marketing, the same can’t be said about the wave of “illegal” shoes that is flooding the roadways on the feet of runners. Super shoes have proven a true performance boon to both elites and recreational runners on race day. Now the tech has trickled down to shoes for daily runs, ushering in super-thick, though still permissible, shoes that have created their own category: super trainers.

What Is a Super Trainer?

Technically, a formal definition doesn’t exist. But we’ll establish some general parameters.

Super trainers share many of the same qualities as super shoes built for race day: a tall stack height, efficient midsole geometry, high-powered super foam, and usually some sort of plate. But these trainers aren’t meant for racing, like a Nike Vaporfly or Saucony Endorphin Elite—they’re designed for everyday mileage.

Super shoes for racing have to balance cushioning and propulsion, but still be lightweight. Super trainers, though, can have beefier constructions that help to extend their life spans. For example, shoe brand On guarantees only four marathons from the Cloudboom Echo 3—that’s little more than 100 miles. Super trainers can handle more mileage, and should have the typical 300- to 500-mile range of a normal running shoe.

To do that, they may have more outsole rubber for durability. Their uppers are usually softer and thicker than a racing shoe’s, as well, with comfortably cushioned ankle collars and tongues. They tie up with sturdier laces and offer a more forgiving fit overall, closer to what you’d expect from a workhorse daily trainer. And, since super trainers aren’t made to toe a starting line, brands can pile on midsole foam in excess of the 40mm limit imposed by World Athletics.

But they’re more than just extremely cushioned running shoes. Super trainers have additional mechanisms and “super foams” geared toward running efficiency and energy return, explained below.

Anatomy of a Super Trainer

If we break down a super trainer into its key components, we see a recurring theme: a stack of super foam in the ballpark of 40mm (or more), a carefully sculpted midsole shape for propulsion, and a plate that harnesses those pieces and holds it all together. This is the tech that puts the “super” in super trainers; it needs to interact with the foot and the rest of the kinetic chain in specific ways to deliver the intended ride and energy return. 

Here’s what’s happening inside the midsole under your foot, and how these elements work to boost your stride. 

1. Rocker Geometry

When we talk about a rocker sole, we’re describing the curvature of the bottom of the shoe’s sole. Both the heel and the toe curve upward, away from the ground, to give the shoe a more rounded base. The result is a shape like that you’ll find on a rocking chair. This is needed because the shoes are so thick, they don’t bend under the forefoot for a smooth transition during your gait cycle. 

Shoe developers can also manipulate the inflection points of the rockers around a runner’s pace and foot strike to potentially manipulate transition time. Usually, you’ll find the most aggressive rocker designs in racing shoes. Still, pronounced rocker soles on super trainers are essential to make transitions comfortable. 

→ How do rocker soles work?

Rocker soles in shoes function to mimic the natural rockers of the foot to make us feel more efficient. The foot has three functional rockers—the heel (first), ankle (second), and forefoot (third)—that we use while walking and running. The heel bevel in a shoe prepares the foot to contact the ground and smooths out the shoe’s ride when you land. Forefoot rockers assist movement during toe-off, which generally means the toes and ankle joint don’t have to work as hard. 

For some runners, a stiff rocker sole can decrease demand on the calves by transitioning effort upward to the knee and hips. A runner’s experience will depend on their specific biomechanics, where the rocker is placed, and how their footstrike contacts it.

2. Super Foam

Polyether Block Amide, or PEBA, is a common foam compound for super trainer midsoles. (A popular trade name for the material is Pebax, made by a company called Arkema.) It’s the basis for foams like Nike ZoomX, Saucony Pwrrun PB, Puma Nitrofoam, and Asics FF Blast Turbo. Many of those brands leverage the same foam used in their top-tier racing shoes for their super trainer models.

Right now, PEBA-based foams lead the way for energy return. While current research and our own testing indicates that supercritical EVA and TPU blends are also impressive, PEBA has the edge more often than not. Why? It’s lighter than TPU and far softer and bouncier than supercritical EVA. Some iterations are firmer than others, depending on which brand’s flavor you try.

→ How does foam work?

Cushioning serves to absorb shock upon landing and provide overall comfort while running, but it can also return energy to the runner and stabilize the shoe. PEBA foams are especially lightweight, so brands can pile it on—both in thickness and in width—without the same weight penalty applied when using EVA or TPU materials. The additional width is just as important as the height. These shoes often need a wide platform of midsole material to remain stable.

Every brand’s PEBA-based foam compresses at a different rate, with varying amounts of responsiveness, so each offers a unique benefit based on the runner. For example, runners who land with lots of force can bottom out and crush a foam that’s too squishy, so they may prefer a firmer platform. A harder midsole can offer more support without any additional stability elements. On the other hand, a softer foam can provide more comfort, and research suggests that it may have a protective benefit for lighter runners. 

Keep in mind that dozens of pieces within a shoe, as well as countless runner-specific characteristics, come together alongside a super foam to deliver its specific ride and response. It’s not always possible to parse each element individually.

3. Plates

Not every super trainer has a plate in its midsole, but it’s increasingly common. That’s because—regardless of whether it’s made from TPU, EVA, PEBA, carbon fiber, or a mix—a plate stiffens the midsole and can add support. It may also give the ride some extra pop, but it largely functions to stabilize the shoe. The Adidas Adizero Prime X 2 Strung, which has a heel stack height of 50mm, requires two stiff carbon-infused plates.

Some shoes need less support and utilize pliable materials with thinner rod constructions or forgo full-length plates for ones that extend only halfway along the midsole.

→ How do midsole plates work?

While plates can add propulsion, research suggests that the true hero is the foam itself. A plate mostly serves to “facilitate motion and add stiffness to the sole to balance out the softer compliant foams,” says Matt Klein, DPT and founder of the Doctors of Running website and podcast.

He explains that the effects of stiff-plated shoes are not clear-cut. “Everything we know [about super trainers] is applied from super shoe and maximal shoe research. These shoes shift work up to the knees and hips. The ankles may do less, but that doesn’t always apply. If the shoe is too stiff, the ankles will actually end up doing more work. But once a midsole gets so thick, it may not need a plate; the amount of material naturally stiffens the ride.”

What Are the Benefits of Super Trainers?

Simply put, these shoes are so much fun to run in. They can lend a bounce to your stride that feels like bounding on a trampoline. And since the springy sensation and high energy return can help you move more efficiently, running fast feels easier.

Plus, a review of 63 research studies concluded that these trainers can also help attenuate shock and dampen some of the hard impacts from training. So, runners recover from hard efforts more quickly; they’ll lace up the next day feeling fresher and less sore than if they’d worn regular running shoes. And for those eager to increase mileage, this may allow some runners to increase their weekly workload with less fatigue and fewer aches and pains.

“These have the benefit of having similarities to super racing shoes. These shoe types certainly increase the capacity of work you can do, so I suspect those running higher miles will probably benefit most from these,” Klein speculates.

But, the recovery boost from super trainers can make it tempting to tack on too many miles too soon or overcook the pace on easy days. “Just because you are less sore does not mean you are at a lower risk for injury. You can still get injured with overdoing things,” Klein says.

Our wear-testers report that they’re able to run faster paces with less effort in super trainers, but it’s still important to keep easy jogs relaxed. Double-check your training log and pull back on the reins if you notice spikes in mileage or intensity outside your typical training volume. 

Are There Any Risks to Super Trainers?

Though they feel great, super trainers can have an impact on our natural gaits and biomechanics. “One of the injury risks for this shoe type is that it is so different from normal mechanics and footwear. The current evidence from super shoes and super-max stack-height shoes is that we tend to stiffen our legs in taller, softer shoes,” Klein says. “This is not bad short-term, but some evidence suggests long-term super-max stack-height shoes can actually increase joint loading due to that stiffening.”

“I suspect running in them a ton will cause less joint motion, as the body will stiffen up to find stability as shock absorption isn’t needed. This may be great for a recovery run/faster run, but trying to transition back to normal shoes can take time if you only run in these and super racing shoes.” Klein recommends making the transition slowly to avoid injury and keeping more than one pair of running shoes in your rotation. 

“I do suspect that with the workload being shifted up to the knee and especially the hip, there may be an increase in injuries in those areas. The hip still has to work harder being on a softer, less stable surface. So, those with hip instability and strength issues may want to avoid super shoes, at least until these issues have been addressed,” Klein says. New runners should focus on building strength and experience before experimenting with super trainers.

There is little doubt that these shoes have effects at the point where our feet meet the midsoles as well as farther along our kinetic chains. Super trainers shift more of the workload of running to the hamstrings, which means that you won’t engage the calves and lower leg muscles as much. Moving some of that effort to larger muscle groups can be beneficial for some runners, like those who are struggling with calf or Achilles tendon injuries. But those who have a nagging hamstring strain may need to be wary. Whether or not it’s your goal, those upper leg muscles will receive more of a workout.

At the very least, one thing can be said for sure. It’s that all the foam underfoot is going to put a lot of distance between your foot and the ground. This limits the amount of ground feel you receive from the shoe. It can be easier to wipe out if you’re hopping a curb on a night run. And on rain-slicked sidewalks or technical trails, it can be tough to steer a thick and bulky midsole. If you’re prone to ankle rolls or need a keen sense of where and how your foot is landing whenever you touch down, a super trainer might not serve you well.

Will I Really Get DQ’d in a Race?

It depends. If you’re an elite runner, absolutely. But if you’re going for a 3:10 BQ, it’s unlikely. Ethiopian runner Derara Hurisa won the 2021 Vienna Marathon in 2:09:22 but was disqualified when race organizers found he’d raced in the Adidas Adizero Prime X, a different shoe than he’d declared on his prerace form. Another runner at a fall 2023 half marathon was disqualified after winning in the same shoe. 

Our Favorite Super Trainers

Running shoes aren’t cheap. Maxed-out midsoles with top-end shoe tech only add to the bill. Most super trainers will cost you $180 at least, and there are options to be had for well over $200.

Jakob Ingebrigtsen brought his remarkable 2026 season to a fitting close on home soil, winning the men’s street 1500m at the inaugural Runfest Norway in Sandnes on Friday.

Competing in front of an enthusiastic hometown crowd, the Olympic and world champion took control of the race from the early stages and maintained his authority through the finish, stopping the clock at 3:40.7.

Andreas Fjeld Halvorsen followed in second in 3:43.3, while Sigurd Tveit completed the podium in 3:47.8.

The unusual street race added another dimension to the occasion, with 273 runners taking part on the same road and sharing the course with one of Norway’s most accomplished distance runners. For the recreational participants, it offered a rare opportunity to compete alongside Ingebrigtsen in an event that brought elite athletics and mass participation together.

The victory also provided a fitting final chapter to a season that began with significant uncertainty for Ingebrigtsen. After undergoing major Achilles surgery in February, the Norwegian was forced to miss a substantial portion of the summer campaign as he worked his way back to full fitness.

His return, however, quickly developed into another championship-winning chapter. In Birmingham, Ingebrigtsen captured European 5,000m gold before adding another major title at the inaugural World Athletics Ultimate Championship in Budapest, where he won the 5,000m.

Those performances transformed what could have been a disrupted season into another year defined by championship success and a determined return to the highest level.

Now, with the Sandnes victory added to his 2026 record, Ingebrigtsen closes the year exactly where it began in spirit — overcoming adversity, rebuilding his form and once again competing at the front.

From Achilles surgery in February to major championship victories and finally a 1500m win before his hometown crowd, the Norwegian has given his 2026 season a memorable final scene.

Olympic 100m hurdles champion Masai Russell has announced her engagement to longtime partner Robert “Robbie” Springfield, adding a major personal milestone to the remarkable journey of one of America’s leading track and field stars.

Russell shared the news with her followers, revealing that Springfield had proposed and that she had accepted. Reflecting on their relationship, the Olympic champion described him as her best friend and expressed her excitement about spending the rest of her life with him.

The couple’s relationship dates back to their college years at the University of Kentucky, where both were student-athletes and competed in track and field. Russell established herself as a standout hurdler, while Springfield competed in the long jump, giving them a shared understanding of the demands, sacrifices and pressures that come with pursuing success in athletics.

Springfield has since transitioned from competition into coaching. A former collegiate long jumper, he is now part of the coaching staff at Morehead State University, where he works with the programme’s sprinters and jumpers.

Their relationship has developed alongside Russell’s rise to the top of the sport. The defining moment of her career came at the Paris 2024 Olympic Games, where she captured gold in the women’s 100m hurdles, securing her place among the sport’s Olympic champions.

Away from competition, Springfield has remained a familiar part of Russell’s journey, sharing in the demanding periods of training and competition that accompanied her pursuit of Olympic success. Their connection has consequently grown from a college athletics relationship into a long-term partnership.

The engagement now marks another significant chapter for Russell, this time away from the track. After reaching the pinnacle of her sporting career in Paris, the 100m hurdles champion is beginning a new phase of her personal life alongside a partner who has been part of her journey since their university days.

From competing on the same collegiate stage to building a future together, Russell and Springfield’s story has evolved alongside two careers shaped by track and field. The Olympic champion will now balance this new personal chapter with her continuing ambitions in athletics

The women’s race at the 2026 TCS Amsterdam Marathon is shaping up to be one of the most competitive editions in recent years, with a deep international field set to take on the fast Dutch course on Sunday, October 18.

At the centre of the contest will be four Ethiopian athletes who have already broken the 2:20 barrier, creating the prospect of a fascinating battle for victory and a possible assault on the course record of 2:16:52.

Defending champion Aynalem Desta will return to Amsterdam looking to retain her title after producing the biggest performance of her career at last year’s 50th edition. Desta won in a personal best of 2:17:37, establishing herself among the leading marathoners in the field and setting the benchmark for this year’s contenders.

Standing in her way will be fellow Ethiopian Meseret Belete Tola, a former Amsterdam champion who knows exactly what it takes to succeed on the course. Belete Tola captured the 2023 edition in 2:18:21, and her return adds another layer of experience and proven quality to an already formidable lineup.

The field also includes Mestawut Fikir Truneh, who arrives with an impressive marathon pedigree. Truneh finished runner-up at the 2024 Berlin Marathon in 2:18:48, demonstrating her ability to compete at the highest level on one of the world's major marathon stages.

Completing the quartet of sub-2:20 Ethiopians is Buze Diriba, whose personal best of 2:19:34 places her firmly among the leading contenders. With four athletes possessing credentials below 2:20, the race is likely to develop into a tightly contested battle from the opening kilometres.

The depth extends well beyond the leading quartet. Desi Jisa Mokonin, representing Bahrain, Yeshi Kalayu Chekole of Ethiopia and Nazret Weldu Gebrehiwet of Eritrea have all established themselves as serious marathon competitors with performances approaching the 2:20 mark.

Another major name to watch is Abeba Aregawi, the former 1500m world champion representing Sweden. Aregawi has successfully transferred her talents to the marathon and made headlines earlier this year by setting a Swedish national record of 2:23:12 on her debut. Her presence adds another intriguing dimension to an already high-quality field.

Amsterdam’s marathon course has consistently provided an opportunity for elite athletes to produce fast times, and this year’s women’s lineup has the depth to turn the race into a genuine test of both championship racing and outright speed.

With four athletes already inside 2:20, two former Amsterdam champions returning to the start line and several other accomplished marathoners ready to challenge them, the battle is expected to remain open deep into the race.

The ultimate target will be the Amsterdam women’s course record of 2:16:52. Whether the leading contenders can threaten that mark remains to be seen, but the quality assembled for October 18 ensures that the record will be firmly in the spotlight when the race reaches its spectacular finish inside the Olympic Stadium.

The 2026 Valencia Half Marathon is shaping up to be a thrilling contest of speed, endurance and tactical brilliance, with some of the world’s finest road runners set to converge in Spain on October 25.

Kenya’s Daniel Ebenyo and Alex Matata will be among the leading contenders, facing a formidable Ethiopian challenge spearheaded by Jemal Yimer and Tadese Worku. The field also features Rodrigue Kwizera, who boasts the fastest personal best among the leading entrants at 58:16.

Ebenyo arrives with a personal best of 59:04, placing him firmly among the athletes capable of sustaining a demanding pace over the 21.1-kilometre distance. Matata, who owns a 59:11 best, adds further Kenyan strength, while Andrea Kiptoo brings another sub-60-minute credential to the race.

Yimer has already established himself as one of the fastest athletes in the field with a 58:33 personal best, while Worku has clocked 58:35. Kenya’s Owen Korir, with a best of 58:58, further underlines the remarkable depth of the men's lineup.

Valencia Half Marathon 2026 Entries

1. Rodrigue Kwizera (Spain) — 58:16

2. Jemal Yimer (Ethiopia) — 58:33

3. Tadese Worku (Ethiopia) — 58:35

Kwizera, who finished second in Valencia last year, leads the field on paper and will be seeking another standout performance on the famously fast Valencia course. With several athletes carrying sub-60-minute credentials, the race has the ingredients for an aggressive battle from the opening kilometres.

Beyond the headline names, the men’s field is deep and highly competitive, bringing together a strong collection of experienced international athletes with proven ability over the half-marathon distance. With so much quality packed into the lineup, the race promises an intriguing battle in which tactics, endurance, positioning and finishing speed could all play a crucial role in determining the eventual champion.

Yet personal bests will count for little once the gun goes off. The title could ultimately be decided by patience, positioning and the ability to respond when the pace begins to rise in the closing stages. Every surge, every tactical move and every second saved could prove decisive on the road to the finish.

With Kenya, Ethiopia and Spain represented by athletes of exceptional quality, Valencia promises a high-octane men's showdown in which the leaders are likely to be separated by only a handful of seconds. The final kilometres could provide the defining moments of a race packed with speed, ambition and anticipation.

On October 25, the question will be simple: who has the strength to command the streets of Valencia and claim the coveted half-marathon crown?

 

April 19, 1982. The Boston Marathon unfolded under unusually warm, sunny conditions, and by the closing stages, the race had become a private battle between two very different American runners: Alberto Salazar, already one of the biggest names in distance running, and Dick Beardsley, the Minnesota runner who had emerged as a serious marathon contender.

For roughly nine miles, from the Newton Hills toward the finish, Beardsley did much of the leading, with Salazar tucked close behind. Neither man could shake the other. They ran deep into Boston locked together, trading surges and refusing to surrender an inch as the crowds along the course grew louder.

Salazar finally made his decisive move with less than a mile remaining. He opened a small gap, but Beardsley refused to disappear. The Minnesota runner chased him through the final streets, closing again as they approached the finish.

Then came the final sprint.

Salazar held his form and reached the finish first in 2:08:52, with Beardsley only two seconds behind in 2:08:54. It was an extraordinary result: both men broke 2:09 in the same Boston Marathon, and both shattered the previous course record.

The race became known as the “Duel in the Sun,” and it remains one of the most celebrated head-to-head battles in Boston Marathon history. Beardsley had not won, but his performance established him as one of America's elite marathoners.

For Salazar, however, victory came at an enormous physical cost. Immediately after crossing the finish line, he collapsed and required emergency treatment, including several litres of intravenous saline. The combination of heat, dehydration and an all-out effort had pushed his body to the limit.

Salazar's marathon career would never again produce quite the same kind of performance. His celebrated 1981 New York City Marathon victory had produced what was initially considered a world record, although the course was later found to be short. His Boston triumph therefore became one of the defining victories of his career.

Beardsley's story would take an even more difficult turn. Injuries disrupted his career, and after returning to the highest level, he suffered a devastating farm accident in 1989. Further accidents, surgeries and severe physical pain followed, eventually leading to a long battle with painkiller addiction.

He eventually overcame that struggle and transformed the darkest chapters of his life into a story of recovery, resilience and redemption.

That is what makes the 1982 Boston Marathon more than a two-second victory.

For one extraordinary afternoon, Salazar and Beardsley produced a marathon duel in which neither man was willing to give way. One crossed the finish line first. The other finished only two seconds behind him.

Two seconds separated them at Boston. Decades later, their legendary duel remains one of the greatest chapters in marathon history.
