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. 

Some victories are measured by finish times. Others are defined by the obstacles overcome simply to reach the starting line.

For American Paralympic swimmer Ali Truwit, completing the New York City Marathon represented far more than covering 26.2 miles. It was the culmination of an extraordinary journey of survival, resilience, and unwavering determination that began with a life-altering shark attack just two years earlier.

On a crisp November morning in 2025, Truwit crossed the iconic finish line wearing a carbon-fibre running blade, fulfilling a promise she had made while recovering in a hospital bed after losing her lower left leg. The emotional milestone marked another remarkable chapter in one of the most inspiring comeback stories in modern sport.

The road to that unforgettable finish began only days after Truwit celebrated a major personal achievement. In May 2023, she completed her first marathon in Copenhagen alongside her mother. Just ten days later, while enjoying a graduation trip to Turks and Caicos with former Yale swimming teammate Sophie Pilkinton, tragedy struck.

While the pair were snorkelling, a shark attacked Truwit, severely injuring her left leg. Displaying remarkable courage, the two swam approximately 55 metres back to their boat, where Pilkinton—then a medical student—quickly applied a tourniquet that stopped the bleeding and ultimately saved Truwit's life.

Doctors were forced to amputate her lower left leg on her 23rd birthday.

Even in the darkest moments of recovery, Truwit's determination never disappeared. Reflecting on having recently completed her first marathon, she joked with one of the first responders that at least she had managed to run a marathon before the attack. The responder's simple but powerful reply would remain with her throughout rehabilitation: "You'll run another one."

Those words became a source of hope during the long and demanding road back.

Only weeks after surgery, Truwit began learning to walk on a prosthetic limb before gradually returning to the swimming pool. The process was anything but straightforward. The water that had once been her sanctuary became a source of painful memories, yet she refused to allow fear to define her future.

Her relentless work ethic soon produced extraordinary results.

Less than 16 months after the attack, Truwit represented the United States at the Paris 2024 Paralympic Games, producing a sensational performance to claim both silver and bronze medals. Standing on the Paralympic podium was a powerful reminder of how far she had come in such a short period, and she dedicated those achievements to everyone who had helped save her life.

Still, another dream remained unfinished.

The New York City Marathon carried deep personal significance. It was not merely another endurance event but a symbolic return to the city where her life had changed forever. On November 2, 2025, she lined up in Staten Island accompanied by 13 family members and close friends, all proudly representing her nonprofit foundation, Stronger Than You Think. Among them was Pilkinton, the friend whose quick thinking had preserved her life on that unforgettable day in the Caribbean.

Together, they covered every mile of the marathon before celebrating an emotional finish that Truwit later described as being "over the moon."

Completing a marathon on a carbon-fibre running blade presents challenges far beyond those faced by able-bodied runners. The prosthetic demands greater strength from the hips, core, and remaining leg while requiring exceptional balance, coordination, and endurance. Truwit's preparation combined months of disciplined training, patience, and mental resilience as she effectively taught herself how to run again.

Her story extends well beyond medals and marathon finishes.

Inspired by her own recovery, Truwit founded Stronger Than You Think, a nonprofit organisation dedicated to helping individuals overcome physical and financial barriers following limb loss. Recognising that sports prosthetics can cost tens of thousands of dollars and are often not covered by insurance, the foundation provides financial assistance for prosthetic devices, supports water-safety education, and promotes opportunities within Paralympic sport.

The organisation has already helped provide more than 11 prosthetic limbs, delivered nearly $200,000 in direct support, and funded over 4,000 hours of water-safety lessons benefiting more than 700 young people.

Throughout her journey, Truwit has remained refreshingly honest about the emotional challenges that continue to accompany recovery. She has openly acknowledged that healing is an ongoing process and that grief can still come in waves. Rather than portraying an effortless comeback, she has demonstrated that resilience is built through persistence, even on the hardest days.

Her remarkable transformation resonates far beyond elite sport. While few people will ever experience the trauma she endured, countless runners and athletes understand the frustration of injury, disappointment, or rebuilding after adversity. Truwit's journey serves as a powerful reminder that recovery is rarely linear and that courage is often measured by the willingness to keep moving forward despite uncertainty.

Now looking ahead to the Los Angeles 2028 Paralympic Games, Truwit continues to redefine what is possible. She is no longer known simply as the swimmer who survived a shark attack. She has become a Paralympic medallist, marathon finisher, advocate, and symbol of resilience whose story continues to inspire athletes around the world.

Her journey proves that while life can change in an instant, so too can the strength of the human spirit. Sometimes the greatest triumph is not returning to the person you once were, but discovering someone even stronger than you ever imagined possible.
