Pouring fuel on the fire, this press release is not helpful.
Very.. very rarely do I make a specific commentary on a particular shoe or shoe company as you all are aware.
And often I really have to bite my tongue.
But on this occasion, I really think there needs to be some discussion, because rarely have I seen or read an article that is such blatant marketing schtick, with no evidence for statement or qualification/quantification of the numbers presented.
The reason I feel compelled to comment is that over the years I have, many times, been told that running shoe companies are only about marketing and only care about selling shoes.
The industry is a soft target.
I have worked at the research, design and development end of the athletic footwear industry, and I know it is about a lot more than just selling shoes.
Often we go to extraordinary lengths to try to figure out what might protect the athlete and improve performance.
A lot of time and a lot of money is spent trying to achieve these things.. and, over the 30 odd years I have been in the industry I have tried to remain vigilant and make sure that statements made could be backed up with the science of the day (which may not be the science of today).
A little way back, Sneaker Freaker dubbed me the "Bullshit Detector", a title I wear with great pride to this day!
So, I found a recent press release incredibly unhelpful, because it gives ammunition to those who say it is just marketing.
And that has a knock on effect for everyone who is working hard for the benefit of the athlete.
The offending item was a press release from yesterday proclaiming:
"ASICS UNVEILS GEL-KAYANO™ 26 AND FOOT MAPPING DATA TO DEMONSTRATE NEED FOR STABILITY SHOE"
Now many of you know I worked for ASICS for many years, and I promise you, a statement like this on my watch would have gone out over my dead body!
Let's take a look at what has been said, and challenge ASICS to give us some answers!
- It seems clear that the "data' presented is directly linked to the new Kayano 26, a shoe the company describes as a "stability shoe". So, question number one is, how does ASICS define "stability"?
- Next, the official press report makes the following (outrageous) statement
"Marking the launch of the GEL-KAYANO™ 26 shoe, ASICS reveals that of approximately 90,000  runners who participated in ASICS FOOT ID system, 43% have a degree of pronation and could be risking injury without a stability shoe."
3. 43% have "a degree of pronation"??? What does that mean? But to make it look official, it is referenced with a '1'.
The reference straight from the press release is as follows: " 43% of approximately 90,000 male and female runners analysed over a five-year period in ASICS retail stores in the US, Japan and Europe."
Well I am really sorry, but I am going to need a LOT more information than that!
4. "could be risking injury without a stability shoe"????? Show me one single piece of evidence to back up this statement please.
5. And here is the official definition of Overpronation: Your foot lands on outside of heel, then heel rolls inward excessively.
I mean really.. show us your benchmarking ASICS....tell us what overpronation is based on your 90,000 measurements.
Now I am sorry, but to package this as scientific data, when in fact it is just a marketing exercise to promote a shoe does not cut the mustard in 2019.
It may be that useful, even valuable data has been collected that will help us to understand the terms bandied about.
Personally.. I want to see the data.. I want to and need to see the numbers, and, if ASICS really do have an explanation of, or definition for 'overpronation", let's hear it!
ASICS is a great and proud brand with an excellent heritage of innovation and quality.. yesterday's press release has not been at all helpful to underline this history.
