Every shoe can make you run farther and faster. At least what their manufacturers want you to believe.
“Our J-Frame supports and guides your foot without the use of heavy, rigid or unforgiving materials,” reads a promotion from Hoka shoes. “It gets its name from the ‘J’ shape, which uses a firmer density foam to support the inside of your foot and heel. It’s stability plus Hoka comfort.”
Ever since P.F. Flyer’s sent kids dreaming of speed — “shoes guaranteed to make a kid run faster and jump higher” — the goal has been to get us to purchase a competitive edge.
Stakes rose and the velocity of our runners increased. The shattering of the 4-minute mile, the legend of Olympian Steve Prefontaine, the Oscar-winning, cross-country journey of Forrest Gump — all created a cultural image of the runner against the world, a solo unaided by gadgetry, an engine, a horse or a ball.
With one exception: the running shoe.
Running shoes matter
Justin Ter Har will be the first OSU-Cascades undergraduate to begin a doctoral program in OSU’s neuromechanics program. He starts in the fall and is the recipient of a graduate teaching assistantship.
The Seaside High School grad is part of an academic team that delivered the thesis, “Influence of Maximal Running Shoes on Biomechanics Before and After a 5K Run” on June 7 at the American College of Sports Medicine Northwest Chapter conference.
Ter Har, 24, knows the joy of running, first developing an interest as a freshman in Bend. “Competing against myself every day was an important thing to me,” he said. “Now I run every other day about five to seven miles.”
Locally, he likes to run at Gearhart’s Del Rey Beach.
Ter Har and co-author Christine D. Pollard studied the impact of shoes on a runner’s lower extremity biomechanics — actions of the ankles, knees, hips — important for clinicians to reduce injury.
‘Born to Run’
Ter Har’s thesis offers not only a mini-buying guide, but a history lesson.
In the early 2000s, author Chris MacDougall’s “Born to Run” inspired runners to emulate the barefoot style of Native Mexicans who could run distances of up to 100 miles at incredible speed.
Madison Avenue touted the image, with the introduction of the minimalist running shoe and claims that a lack of cushioning would reduce injuries by promoting a more natural foot-strike pattern. The weekend warrior could opt to run barefoot or in a minimalist shoe like a Merrill Glove, with no “heel to toe” drop and no midsole cushion.
The industry pivoted the other direction as the company Hoka One One introduced a “maximal” running shoe, thought to reduce the risk of injury with a highly-cushioned midsole.
“The sweetest cushion” is how a 2016 television ad illustrated it, with “Mallowman,” a giant running marshmallow in a white padded suit reminiscent of the Michelin Man, racing all over town to a doo-wop soundtrack, leaping over sidewalks and little white dogs.
Ter Har and Pollard sought to measure the loading force impacts of the maximal and the traditional shoe.
In the study, 15 female recreational runners, from age 23 to 51, with a mean age of 34, ran a minimum of 15 miles per week. Two shoes were chosen for comparison: the maximal Hoka One One and a traditional New Balance.
Participants attended the biomechanics laboratory for two separate testing sessions, with seven to 10 days between sessions.
For one of the testing sessions, the participants wore the neutral running shoe. For the other, they wore the more cushioned.
What surprised Ter Har and Pollard was that despite their cushion, lower extremity impacts of the cushioned Hoka One One were greater than the traditional shoe, a phenomenon Ter Har called “totally counterintuitive.”
Runners should consider this potential increased risk when choosing shoes, authors concluded, although more work is necessary to better understand the longer-term impact of maximalist shoes.
Ter Har wears an Altra Superior 3.5, with “a little bit of cushion,” considered a partial minimalist shoe.
Meanwhile, after his June commencement, he plans to continue his studies as a postdoctoral scholar and graduate teaching assistant.
“I’m interested in footwear in preadolescent children,” Ter Har said. “How an implementation of a minimalist shoe in children could actually make a large effect on running-injury risk down the road.”
