Study shows BOA’s dial-based fit system improves trail running performance

The first running shoes were created roughly 50 years ago. Compared to running shoes today, nearly everything has changed. Outsoles are thinner, lighter, and more durable; midsoles are far more cushioned and responsive; and uppers are no longer leather but crafted of thin, breathable, engineered mesh or knits. One element, however, has remained essentially the same: laces. Today’s shoes, by and large, still use a long, thin cord crisscrossed across the instep to tighten the upper over the foot.

With all the technological advances elsewhere in shoe design it’s hard to believe that no one has come up with a more effective way of securing and holding the foot than by yanking laces through eyelets and tying them in a complicated bow that we learned when we were in preschool. Not only is the method cumbersome and imprecise, but it is also unreliable, coming undone at inopportune times far too often.

Truth be told, new tech has been developed but not widely adopted. Designers have tried various Velcro-type closures and stretchy uppers or laces. Others have gone with pull-cord designs like the Salomon Quicklace system, where you tighten the shoe by pulling on a thin, slick lace and securing it with a clip. While all improve convenience, it comes at the cost of control and comfort for many runners.

One prominent alternative gaining traction is the BOA fit system that uses a ratcheted dial to pull thin laces through guides to tighten the upper. Having tried several trail shoes outfitted with BOA fit systems, I’ll admit I am a fan. In my experience, the BOA system addresses many of the limitations of traditional laces: tightening is convenient and smooth, with micro-adjustments dialed- and locked-in with precise clicks. And, rather than the traditional top-of-the-foot web of laces buffered by a padded tongue, the BOA system tightens panels—custom-designed for each shoe model—that wrap around the foot and hold it comfortably and securely.

Besides convenience and comfort, a new study—that was, it’s worth noting, funded by BOA and carried out by the BOA-sponsored Performance Fit Laboratory—suggests that better lacing can also improve performance. A peer-reviewed white paper published by Frontiers in Sport and Active Living details the study that revealed improvements in stability, agility, and speed on a technical trail when wearing a shoe outfitted with the BOA PerformFit Wrap closure system over the identical shoe with traditional lacing. Despite the conflict of interest and some inherent limitations in the methodology, the study seems sound, and the results are intriguing.

In designing the study, the researchers chose to assess performance in an actual trail-running setting rather than inside a lab. Thirty runners (15 male, 15 female) ran a one-mile loop of a technical trail in Red Rocks Park near Denver, Colorado four times—twice in a pair of La Sportiva Cyklon with the BOA wrap system and twice in the identical shoe retrofitted with traditional top-of-the-foot laces— in randomized, counterbalanced order. During each run, scientists used accelerators and gyroscopes, pressure-sensitive insoles, heart-rate monitors, and GPS trackers to gather biomechanical metrics on the runners. After the test, participants answered questions on the shoe’s fit and performance on each section of the trail.

I was curious who tied the laces and who controlled the tension on both laces and BOA fit system, so I asked Dan Feeney, the BOA-employed biomechanics PhD who directed the study. He said that, in keeping with the “ecologically valid conditions” of the study, they let runners lace their shoes to their preference. “This is more representative of what runners will experience in the real world, so we prefer to test that way,” Feeney said.

When the numbers were crunched, the wrap-equipped shoe was shown to increase ankle stability (reducing the velocity of inward rotation) by five percent, improve heel hold by two percent, and improve running speed on all sections of the trail (uphill, downhill, and level) by one percent—with no increase in effort. In addition, the test runners rated the wrap shoe a better choice for each section of the trail, and said it fit better and inspired more confidence.

Feeney wasn’t surprised by the results, crediting the improvement to the superior fit of the engineered wrap.

“The overlapping panels’ configuration that we designed specifically holds the foot differently from laces,” he said. “The targeted hold over the instep using a wider panel enables force to be spread over a wider area, reducing pressure points. This enables superior fit by pulling the heel back into the heel pocket and ultimately providing better foot-shoe coupling.” This better hold, Feeney believes, is what improved the runner’s stability and helped them to run faster.

Given my experience with BOA-equipped shoes, I too wasn’t surprised that they provided a better hold, but I wouldn’t have predicted the improved speed. It does make sense, however, that not slipping around in a shoe would make each stride more effective. Granted, a one percent improvement isn’t much, but, as we’ve learned with four percent, going faster without increasing effort is a path to PRs.

Before we get too excited, consider that the real-world structure of the study reduces control of all the variables and the likelihood that results can be reproduced. The paper also acknowledges the limitation that everyone involved in the study was aware of what type of lacing they were testing at all times, which could bias the results.

Even with the limitations and biases, however, this study is a reminder—in a world obsessed with the propulsive properties of foam and plates—that a shoe is a complete system and every element, even fit, affects performance. Rather than increasing midsoles to dangerous heights, perhaps designers could spend more energy improving the connection between the shoe and the foot.

BOA has made a good start, although there are some drawbacks. One limitation on the Cyklon and other one-dial shoes is the inability to vary the tension on different parts of the foot. With traditional laces, I can leave the lower eyelets loose while tightening those closer to the ankle—albeit clumsily and imprecisely. The BOA dial, in contrast, tightens the entire system at the same rate. While the independent wrap panels are designed to optimize the force on each section, they don’t allow for individual foot-shape variations and fit preferences (except on shoes with two BOA dials, where each tightens a different set of panels wrapping the top and bottom of the instep—a significant improvement in the technology in my opinion). BOAs are also more expensive than laces, and, admittedly, they look geeky and out of place if you’re wearing your running shoes for anything other than running, which most people do with their road shoes.

So it may be some time before we see BOAs on anything but high-performance trail shoes. But on my morning run today, as I re-tied my laces for the second time and still felt unhappy with the tension, I longed for a day when I could dial in the fit on all my shoes. 

Melissa Jefferson-Wooden delivered a sensational performance in Budapest, storming to victory in the women’s 100m at the inaugural World Athletics Ultimate Championship in a breathtaking 10.62 seconds.

The American produced a superb display of acceleration and composure to claim the World Ultimate Championship title while recording the fastest women’s 100m time in the world this year. Her 10.62 mark underlined her exceptional form and placed her firmly at the top of the global sprinting hierarchy.

Jefferson-Wooden controlled the race through the decisive stages and maintained her form all the way to the finish to secure a statement victory against a field packed with championship pedigree. She crossed the line ahead of Olympic champion Julien Alfred, who clocked 10.74 seconds with a -0.2 m/s wind, while Sha’Carri Richardson took third in 10.76.

Women’s 100m Final

1. Melissa Jefferson-Wooden — 10.62

2. Julien Alfred — 10.74 (-0.2 m/s)

3. Sha’Carri Richardson — 10.76

The victory was especially significant given the quality of the opposition. Jefferson-Wooden held her nerve against Alfred and Richardson, two of the most accomplished sprinters of the current generation, to produce the fastest performance in the world this year when it mattered most.

Alfred once again demonstrated her consistency at the highest level by taking silver, while Richardson completed an all-star podium in a race that brought together three of the biggest names in women’s sprinting.

But beyond the time, the title and the celebration, one of the most touching moments came after the race when Jefferson-Wooden embraced her father, Melvin, in an emotional celebration.

Their moment carried a deeply personal meaning. When Melissa was just 17 years old, she donated her stem cells to help her father undergo a bone marrow transplant after he was diagnosed with myelodysplastic syndrome. Years later, the two shared an unforgettable embrace in Budapest after she had become the World Ultimate Champion.

For Jefferson-Wooden, however, the evening was about far more than a medal. It was the culmination of an extraordinary journey, now highlighted by a world-leading 10.62 seconds on one of the biggest stages in athletics.

With the Ultimate Championship title secured and her father by her side, Jefferson-Wooden leaves Budapest with more than being an ultimate champion. She leaves with momentum, confidence and a powerful statement of intent — turning a high-profile showdown into one of the defining sprint performances of her season.

Audrey Werro has added another major title to her extraordinary season, storming to victory in the women’s 800m at the inaugural World Athletics Ultimate Championships in Budapest.

The Swiss star delivered a commanding performance, taking control from the opening gun and refusing to surrender the lead as she powered through an absorbing battle against two of the biggest names in the event.

Werro stopped the clock at 1:55.88 to become the Ultimate Championships 800m champion, producing another statement performance on one of the sport’s newest and most prestigious stages.

Behind her, Great Britain’s Keely Hodgkinson fought her way to second in 1:56.26, while the Netherlands’ Femke Broeders-Bol completed the podium in 1:56.74.

The result once again brought together the same formidable trio that featured on the podium at the European Championships, but Werro again proved to be the athlete who could rise above the challenge when it mattered most.

Her Budapest triumph is the latest chapter in a season that has already included records, a successful Diamond League Trophy defence and European Championship gold. Now, she can add the Ultimate Championships crown to a growing list of accomplishments.

Werro’s consistency has been particularly impressive in an 800m event packed with elite talent. Rather than simply relying on a fast finish, the Swiss athlete showed her authority by taking the initiative from the beginning and maintaining enough strength and composure to hold off Hodgkinson and Broeders-Bol all the way to the line.

The victory also underlined the remarkable depth of the women’s 800m, with three athletes separated by less than a second at the finish. Hodgkinson’s 1:56.26 and Broeders-Bol’s 1:56.74 showed just how fiercely contested the race was, but Werro’s decision to dictate the pace ultimately gave her the decisive advantage.

For Werro, this was more than another medal. It was another opportunity to demonstrate that her rise is no passing moment. On a stage featuring established champions and elite rivals, she once again produced the performance required to claim the biggest prize.

For Hodgkinson, the silver medal adds another major podium finish, while Broeders-Bol once again demonstrated her ability to compete with the very best over two laps.

But the spotlight in Budapest belonged unmistakably to Werro.

With another championship crown secured, the Swiss star has strengthened her claim as the athlete setting the standard in women’s 800m running. This is Audrey Werro’s era — and the rest of the field is chasing.

Busang Collen Kebinatshipi has delivered another sensational performance, storming to victory in the men’s 400m at the inaugural World Athletics Ultimate Championship in Budapest.

The reigning world champion stopped the clock at an astonishing 43.39 seconds, smashing his own Botswana national record and moving to fifth on the world all-time list.

Kebinatshipi produced a commanding finish to pull away from his rivals and secure the Ultimate Championship title. American star Rai Benjamin finished second in 44.15, while Jereem Richards of Trinidad and Tobago completed the podium in 44.23.

1. Busang Collen Kebinatshipi — 43.39 NR

2. Rai Benjamin — 44.15

3. Jereem Richards — 44.23

The performance is even more remarkable considering that Kebinatshipi had already rewritten the Botswana record just one week ago in Brussels, where he ran 43.40. In Budapest, he lowered that mark by another 0.01 seconds to establish a new national record of 43.39.

That improvement has also propelled the 22-year-old into rare territory. His latest time now ranks him fifth fastest in history over 400m, placing him among an extraordinary group of athletes who have broken the 43.40 barrier.

Kebinatshipi's victory also caps an extraordinary season for the Botswana star. After establishing himself as a global champion, he has continued to demonstrate that he belongs among the very best one-lap runners in the world.

And there is a major reward for his historic night in Budapest: Kebinatshipi walks away as the Ultimate Champion and $150,000 richer.

From another national record to a place among the five fastest 400m runners ever, Kebinatshipi has turned an already remarkable season into something truly special.

Botswana has its latest sprinting superstar — and Kebinatshipi is showing that his ceiling may be even higher than anyone imagined. 

Marileidy Paulino once again proved why she is the undisputed queen of the one-lap event, powering to victory in the women’s 400m at the inaugural World Athletics Ultimate Championship in Budapest.

The Dominican Republic superstar produced a sensational 49.07 seconds to claim gold, pulling decisively away in the final straight and holding off a fiercely competitive field to extend her remarkable unbeaten run.

Paulino delivered her trademark combination of controlled speed and devastating finishing strength. She remained firmly in contention through the opening stages before unleashing her decisive move down the home straight, where she quickly opened a gap on her closest challengers.

Norway’s Henriette Jæger mounted a strong challenge but could not match Paulino’s finishing speed, crossing the line second in an impressive 49.28. Jamaica’s Nickisha Pryce completed the podium after clocking 49.56, ensuring that three of the world’s leading 400m talents occupied the medals.

The result once again underlined Paulino’s extraordinary consistency at the highest level. She entered Budapest as the world leader after running 48.48 in Paris in June, a performance that also set a Diamond League record. She subsequently remained unbeaten throughout her Diamond League campaign, closing the circuit with a meeting-record 48.64 in Brussels.

Budapest has also become a special venue in Paulino’s career. Three years ago, at the same National Athletics Centre, she captured her first individual world title, marking the beginning of another dominant chapter in her career. She later added Olympic gold in Paris in 2024, further establishing herself among the defining 400m athletes of her generation.

The inaugural World Athletics Ultimate Championship has brought together the sport’s biggest stars in a new winner-takes-the-spotlight format, with Olympic and world champions, Diamond League winners and leading performers competing for ultimate honours.

For Paulino, the occasion once again ended with Ultimate Crown on her arms.

With 49.07 seconds, she did more than win another major 400m title. She delivered another statement of authority, powering through the final straight with the confidence and speed that have made her one of the most dominant figures in modern women’s athletics.

Marileidy Paulino remains unbeaten, remains relentless and, once again, remains the queen of the one lap.

Jakob Ingebrigtsen has made a major decision regarding the remainder of his World Athletics Ultimate Championship campaign, confirming that he will withdraw from the men’s 1500m in Budapest despite producing a sensational performance to win the 5,000m title.

The Norwegian superstar stormed to victory in the inaugural Ultimate Championship 5,000m on Friday night, clocking a season-best 12:59.24 and delivering a devastating finishing kick to defeat Olympic 5,000m champion Cole Hocker and American Parker Wolfe.

Ingebrigtsen’s final 100 metres was arguably the defining moment of the race. The Olympic champion produced a remarkable 12.60-second closing 100m, powering away from the field to secure the $150,000 winner’s prize and underline just how far his fitness has progressed since returning from Achilles surgery.

The victory was particularly significant after what has been an extremely difficult period for the 25-year-old. Earlier in the season, Ingebrigtsen faced serious uncertainty over whether he would even be able to compete at the highest level again. His return has gradually gathered momentum, and his performance in Budapest offered perhaps the clearest indication yet that the Norwegian is rediscovering his formidable racing ability.

But rather than risk pushing his recovering body further, Ingebrigtsen has now opted to step away from the 1500m.

The decision means the highly anticipated showdown with British rival Josh Kerr will not take place in Budapest after all. The two stars had been expected to renew one of the biggest rivalries in modern middle-distance running in the 1500m final.

Instead, Ingebrigtsen is looking beyond the immediate opportunity and towards the bigger picture.

“I’m thinking about 2027… Fitness cannot be faked,” the Norwegian said, signalling that protecting his long-term condition has become more important than chasing another major victory only days after his return to peak-level competition.

The decision comes just one week after an emotionally charged Diamond League Final in Brussels, where Ingebrigtsen finished fourth in the 1500m behind Australia’s Cameron Myers, Kenya’s Phanuel Kipkosgei Koech and American Ethan Strand.

After that race, Ingebrigtsen delivered a fiery assessment of his rivals and questioned the tactics surrounding the pacemaking, particularly involving Hocker. He later acknowledged that there had been “a little too much adrenaline and emotion” when microphones were placed in front of him immediately after the race.

Yet his latest decision shows that beneath the emotion and competitive intensity lies a longer-term strategy.

Ingebrigtsen has already demonstrated that he can compete at an elite level again. His 12:59.24 in Budapest was not simply a victory — it was a statement that the Norwegian remains capable of producing a world-class finish even after months of injury rehabilitation.

Now, however, he is choosing not to gamble with that progress.

For a runner who has spent much of the year fighting his way back from injury, another 1500m race could have offered enormous rewards but also carried unnecessary risk. By withdrawing, Ingebrigtsen is effectively prioritising longevity over one more opportunity for immediate glory.

His message is clear: the comeback is underway, but it will not be rushed.

The 5,000m victory has given Ingebrigtsen confidence, momentum and perhaps, most importantly, proof that his body can once again handle elite competition.

Now comes the harder part — knowing when to stop.

With 2027 already firmly in his sights, the Norwegian has chosen recovery over risk. And after everything he has endured, that could ultimately prove to be one of the most important decisions of his comeback.

Jakob Ingebrigtsen is not walking away from the sport. He is protecting his future in it.
