Before I start this, let me state that it is not intended as a debate between barefoot/minimalist running and trainer shod running. Whilst I am a fan of BF/MR, I don’t practice it solely, and once my broken ankle is cured I aim to return to my practice of BF/MR once or twice a week and my main runs with my dogged trainers.
This post is rather about my amazement that trainer manufacturers are allowed to get away with what they do get away with, regardless of whether or not trainers are bad for you.
I came across a leaflet in my gym last night. I’d just sat on a spin bike for 50 minutes and then had a swim, so I was quite tired. Being tired leads to me generally being cranky, so perhaps I shouldn’t have read this leaflet, but read it I did. The amount of faux-science was staggering, and it worries me that people genuinely are taken in by this kind of language.
The leaflet was for a pair of what I think are supposed to be trainers. The tagline of the advert reads:
The Energy Drink for your feet.
The shoes are fronted by Lewis Hamilton, that well known distance runner, who I’m sure was paid a rather large sum of money to hold them up looking smug. And why shouldn’t he? The shoes he’s wearing are obviously engineered to the highest degree. The diagram inside shows how the sole provides “More Energy”, with the zig zag shaped sole absorbing the impact of your heel strike, sending a wave of energy along the length of the shoe. Right.
And strangely (according to the diagram anyway), the laces apparently provide an “Energy Boost”, designed to help your legs feel fresher.
What is Zigtech?
Feel the shoe with the energy boost, its unique sole propels you forward, while reducing wear and tear by upto 20% on key leg muscles.
I can’t even begin to say how stupid this statement is. How have they measured this 20%?
In addition to this “How does it work?” section..
Absorbs the impact of heel strike Transforms each step into a wave of energy Helps to propel the athlete forward with each step
..contains a worrying statement (perhaps only worrying to someone who has read a lot about the debate between Barefoot/Trainer running, and the science involved). “Absorbs the impact of heel strike” sends warning signals to anyone that knows a modicum about modern running injuries, how the foot is designed, and heel striking is not ideal for running at all. Next “Transforms each step into a wave of energy”, er, I don’t know what to say to that. It’s bullshit. Finally “Helps to propel the athlete forward with each step”, funny. The human foot is perfectly designed to do just that, without all this “fantastic” technology.
Finally, they’re made with Celliant™ fibres. These are a relatively new technology which are designed to take energy emitted from the body and recycle it through the skin, a claim Reebok say with “increase oxygen levels by an average of 7%”. Celliant fibres is a relatively new technology, and like many new scientific products is yet to be fully proved. I’m not saying this is nonsense, but there is very little scientific evidence to support these claims, other than surprisingly the company that developed this technology. To me, it looks like some psuedo-science nonsense that is being used to help sell more expensive running kit, but I’m happy to be proven incorrect on this.
Finally? Whats possibly worse than all this “science”? Just look at them:

I can’t imagine any serious runner ever considering these as being worth while. Which is probably why, in this country at least, they’re fronted by a Formula 1 driver who lives for sponsorship. Tsk.
I’ve asked Reebok for evidence of these claims, but given that they’ve ignored far more noteworthy people than me in the past, I’m not waiting for a reply.
