Minimalist footwear, running technique, and how physiotherapy can help

Who has heard of minimalist running or barefoot running? Maybe a friend has told you to read “Born to Run”, or insisted you get a pair of Vibram shoes? Well… Born to Run is a very interesting read, highly recommend it to any running fans, but picking up a pair of Vibram’s should be done with a bit more caution.
Before we get into the nitty gritty of the minimalist footwear movement, let’s take a very brief look about how you are running and how humans are designed to run.
Running Mechanics 101
A main focus of running mechanics and shoe design, is where we land on our foot when we run.
Generally, people land on three different places when they run: heel, middle of the foot (midfoot), or the front of the foot (forefoot). Heel strike is the most common pattern, making up 72% of the population, 24% of people use a midfoot strike, and only 4% of people use a forefoot strike (Hatala et al., 2013).
Our legs and feet (particularly our foot arches) act like springs when we run. They store energy when our feet hit the ground, and use the energy to thrust us forward. This is critical to efficient running.
When we land on our heel, our spring mechanism is not loaded, so we can’t take advantage of the extra momentum it gives to our next stride. When we land on our forefoot, our spring mechanism is loaded, so we are better able to absorb the force of landing and turn that into propulsive forces to drive our next stride.
Do I need to change how I run?
Is one better than the other? Not necessarily.
We all run on our toes when we sprint, because it’s faster, but it also demands greater leg strength to maintain over long distances.
A recent study found that the majority of elite distance runners have a forefoot or midfoot strike (Hasegawa et al., 2007). And it’s no coincidence that countries which produce some the world’s best distance runners, like Kenya, have higher percentages of barefoot running.
Most of us are not elite runners and can’t maintain a forefoot strike pattern over long distances, so most adopt a heel strike. Some claim a heel strike is an easier form of running (Larsen et al., 2012), and others say easier form does not equal better form.
So, who should be using which stride? Well, unless you are aiming to be an elite runner (sub 16 minute 5km for men or sub 20 minute 5km for females), you should think carefully before changing to a forefoot strike. If your current strike pattern is working well, stick with it. But if you are adamant about making the change, take your time, this is not something to do overnight.
