Vibram Never Lied To Me


So the news broke this past week that Vibram will settle a class action lawsuit for $3.75 million over false claims about the health benefits of FiveFingers footwear. The first internet news story I saw about the suit was from a site called FITTISH, which ran the headline "FiveFingers Maker Will Pay Millions To Suckers Who Bought Its Shoes". Suckers, eh? And then there's the HuffPo piece saying that Vibram "lied to us all". See!? It was all a big scam! I can keep wearing my traditional cushiony running shoes without having to feel like a schmuck for not jumping on the minimalist bandwagon. The self-righteous "told-ya-so" tone of these articles sort of imply the settlement is somehow an indictment against barefoot/minimalist running itself. Talk about being a sore winner...

Well, not so fast. I do not necessarily intend to go to bat for Vibram here, but I should disclose that I've been running in FiveFingers for years and have been, in general, very happy with them. I am not going to provide anecdotal 'evidence' to show how awesome and totally rad FiveFingers are and why everyone should run in them. The fact is, there are plenty of people who probably shouldn't run barefoot or with minimalist footwear. We were not all born to run, unfortunately. There are good biomechanical reasons why some people may be great at barefoot running, while others certainly won't be. These are just cruel facts of biology.

As for lawsuit itself, this is really the crux of it as described by Runner's World:
Valerie Bezdek brought the class action suit against Vibram in March 2012.  She filed her complaint in Massachusetts, the state where Vibram’s U.S. headquarters are located. Bezdek alleged that Vibram deceived consumers by advertising that the footwear could reduce foot injuries and strengthen foot muscles, without basing those assertions on any scientific merit. “The gist of her claim is that Vibram illegally obtained an economic windfall from her because it was only by making false health claims that Vibram induced consumers to buy FiveFingers shoes, and to pay more for them than they would have otherwise,” Harvard Law School professor, John C. P. Goldberg, told Runner’s World at the time of the original filing. Subsequent class action suits were filed against Vibram in California and Illinois, and those were absorbed into Bezdek’s case.
Tribal affiliations aside, I will readily admit that there really isn't a whole lot of scientific evidence surrounding the claim that barefoot running reduces injury rates. This is a difficult thing to study as there are so many factors involved that are hard to control for. All our bodies are different, we all wear different shoes at different times, we all have different running forms, we all run different amounts at different paces across different terrains, and so on. At one time, all running shoes were more or less flat, and people sometimes got hurt while running. Then they made shoes with raised heels and cushioned soles, and more people started running in them. People continued to get hurt. Some folks chose to run barefoot, and a few shoe companies offered various products which allowed for this running style while not compromising on sole thickness or heel-toe drop. People still got hurt.

It's all murky, and there's not a lot of clear evidence about how to avoid injury. Which is precisely why Vibram never should have made any claims that using their toe shoes would strengthen the muscles in the foot and lower leg and reduce injuries. You just don't get to say those things without the objective data to back it up, since people will inevitably get hurt when they get up off the couch and go running, barefoot or otherwise. Their lawyers must have been out to lunch when their marketing team overreached with their claims of potential health benefits. People can and do run differently and efficiently when not using modern running shoes. It's all about impact forces and footstrike, but this does not necessarily have any implications for reducing injury:
If impact transient forces contribute to some forms of injury, then this style of running (shod or barefoot) might have some benefits, but that hypothesis remains to be tested.
That being said, I do not feel Vibram "lied to [me]." At the time I was considering the switch to minimalist footwear, there were lots of things to consider. The least of which were any claims of "health benefits and reduced injury rates". I don't recall Vibram making those claims, and they certainly weren't what attracted me to them in the first place. (Perhaps the explicit claims were removed from their website before I even ordered my first pair a couple years ago.) Nebulous and inconclusive studies notwithstanding, pretty much everything I read about 'barefoot' running (including running in FiveFingers) carried this warning: GO SLOWLY. Transitioning from normal running shoes to minimalist shoes (or no shoes) was a difficult and risky process that required a lengthy acclimation period. To me, this was sound advice that made sense. So I followed it as best I could, though I couldn't help but be a little overzealous at times when the feeling of foot freedom overtook me.


Therefore I will not be seeking to a payout from Vibram as a part of this settlement. Their product has performed well for me and did not fail to meet my expectations. Coincidentally, I had ordered a new pair of FiveFingers from them just a few days before I heard about the lawsuit last week.

The news of this class action lawsuit will probably do little to shake the faith of the Vibram True Believers, and the detractors who never 'gave in' into the barefoot running fad will feel vindicated by the settlement. There may be a few fence sitters out there who will perhaps think twice about experimenting with minimal footwear and the barefoot running style. People will become more entrenched and seek to reaffirm their original positions. This is to be expected.

The lesson here is to always be on the lookout for better and more reliable evidence about footwear and running form so that we can all make informed decisions concerning how we choose to run. We should also be skeptical of any claims made by those who are tying to sell you a product. There will always be risk of injury, and the more you know about your body and how it works should help you reduce that risk. But it would be foolish to think the risk can be completely eliminated. The key is to find what works best for the individual, and that takes practice, patience, and a willingness to learn and reflect.
