Various studies support the pros and cons of each style—so which is correct?
Most of the tenets of good running form are universally agreed upon by coaches, athletes, physiologists, form gurus and shoe designers: an upright postural alignment with a slight forward tilt, a compact arm swing and short strides that result in a cadence of 180 steps per minute or higher.
But the one thing that still seems to be a stickling point is footstrike—how and where your foot hits the ground. Certainly there is a distinct difference between heel-striking, a midfoot-striking gait and running on your forefoot. Various studies support the pros and cons of each style, but the impacts also vary considerably among individual runners. So what’s best for you? Where your foot contacts the ground is much more important than how it contacts the ground, says Bend, Ore., physical therapist Jay Dicharry, one of the country’s leading running gait analysts and running injury experts.
“I look at footstrike as more of an effect than a cause in running form,” Dicharry says. “There’s more to it than just the foot- strike. Just because you heel-strike doesn’t mean you have bad form.”
But, he concedes, runners who are heel-striking are most likely, but not always, overstriding. “By moving the footstrike closer to the body, a lot of runners will land more on their midfoot, but some will still land on their heel, and that’s totally OK,” Dicharry says. “Likewise, there are plenty of overstriding forefoot strikers out there.”
Studies show between 65 and 80 percent of runners are injured every year. Many of those overuse injuries result from a runner applying too much force on a repetitive basis. The way to reduce the chance for injuries is to run with the least possible musculoskeletal stress on your system possible with the least metabolic cost, Dicharry says.
How can you tinker with your mechanics to improve your form? Start by running in lighter shoes with a flatter heel-toe ramp angle (but not necessarily minimalist models) and increasing stride cadence by shortening stride length, Dicharry says. Each of those things will help bring your footstrikes closer to your body, he says.
“The most important thing is that you want your feet to land as close to your body for a given pace as possible,” says Dicharry, the author of “Anatomy for Runners: Unlocking Your Athletic Potential for Health, Speed, and Injury Prevention.”
