Actually not that interesting. The problem is that many healthcare providers are just prescribing orthotics because that's what patients ask for. See it all the time.
If you look into his results, they proved beneficial for the most commonly prescribed reasons for orthotics, plantar fasciitis and tibial stress fractures. But, most of the data he is pulling from were underpowered studies, so the results of his analysis is also underpowered.
Since there are a vast difference in types of orthotics and methodology for using them, such a review article would have to break each type of orthotic down by density of material, reason for prescribing, methodology for fitting orthotics, etc...in which you would have to have an extremely large cohort to do.
Enough for my rant, just tired of news talking about research that is poorly done then spoon feeding it to the public like it is the almighty truth. Considering I'll be a physician soon enough, it also worries me that a lot of my colleagues don't know how to objectively look at research either.
I do agree with you all, for the most part, we don't need any sort of orthotics and that minimalist shoes would probably help the vast majority of people. BUT there are people that orthotics do benefit. I have seen it work for a lot of athletes i have worked with in the past for foot and tibial stress fractures and also for plantar fasciitis. Of course, we prescribed them for the short term and eventually transitioned them back to normal footwear.
Lastly if you are talking about gel inserts and smartfeet sort of stuff, they are nearly worthless if you have properly fitted shoes.
