Each few years, one thing kicks off a debate about whether or not heel hanging is destroying your knees, or whether or not switching to forefoot hanging will resolve all of your harm issues.
The barefoot operating motion made foot strike the defining query of operating type.
The analysis since then has sophisticated the image considerably.
Right here’s what you really must know.
- The three forms of foot strike and learn how to determine yours
- What analysis says about foot strike and harm danger (and why the reply isn’t easy)
- How pace naturally adjustments your foot strike sample
- When altering your foot strike is sensible, and when it doesn’t
What Are the three Kinds of Operating Foot Strike?
Your foot strike sample describes which a part of your foot contacts the bottom first on every step.
Rearfoot (heel) strike: Your heel contacts the bottom first, then your foot rolls ahead by the midfoot and pushes off from the forefoot.
Midfoot strike: The surface fringe of your total foot contacts the bottom without delay, with no pronounced heel or forefoot touchdown.
Forefoot strike: The ball of your foot contacts the bottom first, with the heel dropping down afterward.
Analysis has discovered that 75% of leisure runners heel strike, even at race tempo throughout an elite half marathon.
Midfoot hanging is the rarest sample and the toughest to maintain, because it requires near-perfect ankle positioning all through the gait cycle.
Elite marathoners with each foot strike sample have received world main races.
Does Your Foot Strike Sample Have an effect on Damage Threat?
That is the query that launched a thousand arguments, and the sincere reply is: the analysis is genuinely blended.
A 2012 research from Harvard tracked harm charges of their collegiate cross-country crew and located that heel strikers had harm charges 2.53 instances larger than forefoot strikers over a season.
A potential research of Harvard cross-country runners discovered heel strikers had 2.53 instances extra repetitive stress accidents than forefoot strikers on the similar coaching load.
That quantity will get cited continually. Right here’s what will get not noted.
The runners in that research have been barefoot runners who had already chosen forefoot hanging.
Choice bias runs in each instructions: runners with sure harm histories usually self-select into forefoot hanging, and research that examine patterns inside the similar group present a lot smaller variations.
A number of systematic opinions since 2015 have discovered no constant proof that one foot strike sample causes fewer accidents than one other when coaching load, operating floor, and sneakers are managed for.
The harm query isn’t settled. What’s clear is that the connection between foot strike and harm is way weaker than the barefoot operating wave prompt.
Does Heel Hanging Actually Trigger Extra Impression Pressure?
Biomechanically, sure. However the best way impression power works is extra sophisticated than it seems.
Heel hanging produces a pointy, transient impression transient in the meanwhile the heel contacts the bottom.
Forefoot hanging skips that preliminary spike as a result of the ankle acts as a shock absorber, changing vertical power into rotational power on the ankle joint.
Analysis printed in Nature discovered that habitually barefoot forefoot strikers generated impression forces 2–3 instances decrease than habitually shod heel strikers on the similar pace.
Decrease impression power feels like a transparent win. The power has to go someplace.
In forefoot hanging, the ankle and calf take in the forces that the heel doesn’t.
Because of this runners who change from heel to forefoot hanging with no gradual transition usually develop Achilles tendinopathy, calf strains, and metatarsal stress fractures. The calf and ankle aren’t conditioned for the brand new load distribution.
The place your foot strikes determines which constructions take in impression, not whether or not impression happens.
How Does Operating Velocity Have an effect on Your Foot Strike?
Your pure foot strike sample shifts considerably with pace. This explains a lot of the confusion about what elite runners “do.”
At simple paces, the overwhelming majority of runners naturally heel strike.
As tempo will increase, the sample shifts towards midfoot and forefoot touchdown. Cadence will increase, floor contact time shortens, and the foot naturally strikes nearer to the middle of mass.
Analysis monitoring elite half-marathon runners on the 15km mark discovered that 74.9% have been nonetheless heel hanging at race tempo, a tempo most leisure runners would discover extraordinarily quick.
Sprinters forefoot strike as a result of sprinting mechanics demand it, not as a result of forefoot hanging is inherently superior.
At your 5K race tempo or marathon effort, your foot will naturally land considerably in a different way than at a straightforward coaching jog. That’s precisely what it ought to do.
Ought to You Change Your Foot Strike to Scale back Damage Threat?
For many runners, the reply isn’t any.
Intentionally altering your foot strike is likely one of the highest-risk type interventions obtainable.
A potential research following runners who switched from heel to forefoot hanging discovered {that a} vital proportion developed new accidents through the transition. Stress reactions within the metatarsals and tibia have been significantly frequent.
The hundreds your physique is customized to soak up shift solely while you change your strike sample, and tendons, bones, and connective tissue adapt much more slowly than muscle tissues do.
There’s a greater goal than foot strike: cadence.
Analysis from the College of Wisconsin discovered that rising operating cadence by simply 5–10% diminished loading on the hip and knee by 20–34%, with out requiring any deliberate foot strike change.
A better cadence naturally shifts your touchdown level nearer to your heart of mass, reduces overstriding, and infrequently leads to a extra midfoot-ish touchdown, all with out the harm danger of a compelled transition.
In the event you’re coping with a selected harm that your clinician has traced to your foot strike sample, that’s a special dialog.
However altering foot strike to chase a efficiency edge or forestall unspecified future accidents is never definitely worth the danger.
If you wish to cut back impression forces and harm danger, rising your cadence by 5–10% is safer and better-supported by analysis than altering your foot strike.

When Does Altering Your Foot Strike Really Make Sense?
There are particular eventualities the place a coached transition is price pursuing.
Recurrent forefoot or metatarsal stress fractures in a heel striker: Shifting loading off the heel and redistributing by the ankle could assist, although strengthening the foot and calf concurrently issues simply as a lot.
Persistent Achilles or calf accidents in a forefoot striker: Shifting towards a extra midfoot sample can cut back the load on these constructions, significantly if the forefoot strike is aggressive (operating on the toes slightly than the ball of the foot).
Extreme overstriding mixed with heel hanging: When your foot lands far in entrance of your heart of mass, the mixed braking power and impression spike is massive. Growing cadence addresses this higher than a direct foot strike change, however often each are wanted.
In all of those circumstances, work with a operating coach or sports activities physio, make the change regularly over 8–12 weeks, and cut back mileage by 30–40% through the transition.
Your tendons and bones want that runway.
For extra on how heel hanging and overstriding work together, see Heel Hanging, Overstriding, and Cadence.
75% of leisure runners naturally heel strike, and most elite marathoners do too.
Forefoot hanging reduces the preliminary impression spike, however transfers load to the ankle and calf, that are vulnerable to harm if not conditioned for it.
The proof that altering foot strike prevents accidents is weak. The proof {that a} compelled transition causes new accidents is stronger.
Growing cadence by 5–10% reduces hip and knee loading by 20–34% with out the harm danger of adjusting foot strike.
Solely change your foot strike if a clinician has recognized it as a selected harm trigger. Do it regularly over 8–12 weeks with diminished mileage.
