At ARION we are on a mission to decode human movement. After a decade of research, six years of operation, and thousands of hours of recorded movement data, one thing has become very clear to us. Movement is exceptionally unique.
We all have diverse bodies, varied techniques, unique philosophies and personal goals. All of these elements heavily influence the way we move. Each contributing to our individual biomechanical profile, is what we call, your unique running identity.
To explore this, in this content series we will highlight that there is no such thing as the perfect running shoes. It all depends on your own completely unique biomechanics and your individual goals. We will be testing eight of the latest and greatest running shoes. Utilising our groundbreaking technology shows how one shoe can have two very drastic results on two very seemingly similar people.
We don’t review the shoes based on their general performance. We simply highlight the diverse results generated across different people. Each month we will put a new pair of shoes to the test before finally reviewing it all together with a final summary of our movement experiment.
As always, it’s the same conditions (treadmill), same shoe, same size, same pace, same distance, very different results! First up is the Hoka Mach 5…
HOKA Mach 5
The HOKA Mach 5 is a neutral running shoe with a heel-to-toe drop of 5mm. HOKA has made the shoe very responsive by adding their PROFLY+ construction midsole that is tuned for an energized run. The upper is made out of engineered mesh. The shoe itself is lightweight as HOKA made some changes towards the Mach 4, in the upper and the foam to slightly decrease the weight without reducing the benefits of the shoe.
1. The Runners
Let’s introduce our runners. Runner 1 is Manouk. She runs around once every two weeks for a longer run, and every week a couple of short runs to conduct research for ARION. Her preferred distance is around 5k with a pace between 5:15 and 5:30 min/km. A future goal for Manouk is to finish a quarter triathlon. She likes to run because she wants to stay in shape and doesn’t have time to take part in other sports.
Our second runner, runner 2 is Elzemieke. She runs around three times a week for long runs. Her preferred distance is around 5k with a pace between 6:30 and 6:50 min/km. A short-term goal for Elzemieke is to run a 5k race during the Eindhoven Marathon. Elzemieke likes to run because it clears her mind and to stay in shape.
For both runners, we will compare the HOKA Mach 5 to a baseline shoe. This baseline shoe will be an average of how both runners run. For both runners, the baseline shoe is a neutral running shoe with a lower drop. With this shoe, Manouk is a forefoot lander and Elzemieke is a rearfoot lander. Manouk is neutrally balanced whereas Elzemieke is a little bit more balanced towards her left foot. Both runners have an average cadence for a recreational runner and a nice stability profile where she variates the foot placement whilst landing.
2. The Results
3. The Insights
When listening to a shoe manufacturer, you would expect a shoe to have a certain effect on all runners. For example, experiencing fewer injuries or running more efficiently. Looking at the results, it is probably not that generic. A pair of shoes can make one runner run more efficiently, while it can decrease efficiency in another. Let’s have a look at such a difference.
Footstrike Y and bioload
When looking at Footstrike Y, we see that there is a minimal difference between the HOKA and the baseline shoe for Manouk. The same applies to Elzemieke, there is almost no difference. Manouk is still a forefoot lander and Elzemieke is still a rearfoot lander. The fact that there is no difference can be derived from the lower drop that the HOKA shoe has. A low drop doesn’t influence the footstrike Y compared to the baseline shoe. This means that for the bioload, which is influenced by footstrike Y amongst others, there are also little to no changes between the baseline shoe and both runners. There is still a difference between Elzemieke and Manouk, where Manouk has more biomechanical loading on her calves and feet whereas Elzemieke experiences more biomechanical loading on her lower back, upper legs and knees. These biomechanical loading profiles are typical for both runners and their running styles. A forefoot lander like Manouk is more likely to use experience loading in their calves and feet whereas a rearfoot lander is more likely to use their lower back, upper legs and knees.
Flight time/Contact Time (FT/CT)
The ratio of flight time (time your feet spend in the air) and contact time (time your feet spend on the ground) is interesting to look at when analysing a shoe. A high FT/CT ratio means that the runner is running efficiently by spending less time on the ground and more time in the air. Manouk her FT/CT ratio is not heavily affected by the HOKA shoe compared to the baseline shoe and stays relatively stable, which means that the HOKA doesn’t particularly change her running efficiency. On the contrary, Elzemieke’s FT/CT ratio increased, which means that Elzemieke spends less time on the ground and more time in the air, improving her efficiency.
The HOKA Mach 5 has a high stack height. From the analysis, we can see that the stack height influences the running technique of both Manouk and Elzemieke. Both runners experience longer step lengths compared to their baseline shoes. This can be explained by the stack height, adding length to the legs of both runners, which automatically increases the step length.
Movement is unique.
If we combine the findings, we can conclude that the HOKA Mach 5 is a better fit for Elzemieke than for Manouk. Elzemieke’s FT/CT ratio and step length increased, her step length increased, and her footstrike remained as a rearfoot lander. These key takeaways indicate that Elzemieke’s running efficiency increased effectively when compared to the baseline shoe.
For Manouk, her FT/CT ratio is not heavily affected, her step length did increase, and her footstrike remained as a forefoot lander. Therefore, the HOKA Mach 5 is a lesser fit for Manouk compared to her baseline shoe.
That’s why at ARION, we focus on your unique running identity, combining your individual biomechanics with a specific shoe. Stay tuned as we continue to test another pair of the latest and greatest running shoes every two weeks and start to explore some comparisons between the different shoes that we test.
