How were the tests conducted?
The majority of tests were performed on 5 km distances. A sample group of 10 runners was selected (all size EU 42 / US 8) for each test. 2 separate runs were conducted in a 2-5 day period. Runners were told to restrain from serious exercise between runs, and to not drink alcohol for at least 24 hours prior to the run. Shoes were randomized, our test shoe A or a competitors shoe B. Runs were conducted indoor, in a track and field arena to make sure conditions were the same all the time. We then compared times of test A with test B and performed a Wilcoxon signed rank test of the results. To make sure the test setup was not compromised in any way, we also did tests where shoe A and shoe B tested were identical. In that scenario, results were nearly identical.
Why didn’t you use a standard running effectiveness test
We believe that Sub max tests based on a certain percentage of the VO2 Max isn't the best way to predict running performance. Competitive running isn't only aerobic and that is the simple answer to why they don't work. All out time trials on shorter distances have proved to be a much better predictor of race performance on longer distances. That's why we use time trials.
What do you mean when you speak of a better running feel?
Runners who tested our shoes not only run faster, they get a different and better feeling from running. Most people report that they feel stronger and have an improved posture.
Is there a breaking in period?
Although our shoe is equally effective in forefoot strikers, mid foot and heel strikers, there is a tendency for heavy heel strikers to change their muscle usage pattern. Some have experienced sore calves. Always listen to your body’s response, it’s not to be taken lightly.
Are there any injury risks associated with Airia One?
Apart from some muscle soreness we haven’t come across any injuries during our tests. However, running is associated with some risks of injury. There is, in our opinion, not enough data available today to say anything regarding how the Airia One running shoes relate to running injuries. As always, weather you run in Airia One shoes or any other running shoes, listen to your body’s response, it’s not to be taken lightly.
Is there a social or media community for the Airia concept?
