You've got a book--Born To Run--that won't leave the NYTimes Bestseller list. And you've got every serious/casual runner out there espousing the virtues of minimalist footwear for running. I feel like I run into conversations on the topic at half of the social events I go to; Vibram has made millions of those five-toed shoes; everybody feels smarter for having read that book and worked less foam into their running routine -- and now this guy shows up with a shoe that runs straight against that vibe? That's tough swimming, even if he's right.
Obviously, he should have assented to a far lower royalty rate.
When I run on a minimalist shoe for the first time (or wear hockey skates, or snowboard, etc) I get arch and shin pain.
Your feet will adjust very quickly, especially with some stretching. I also found a small weight loss (10 pounds) helped tremendously.
When I first tried running in VFF shoes I limited myself to 15 minute sessions, and even then my calves were so destroyed walking was stiff for 2-3 days. I slowly eased that limit up a few minutes at a time over the past year, and while I have a ways to go, I can run about 30-40 minutes now and my legs and feet look completely different.
The feet are a complex tangle of muscle, bones, tendons, and nerves. They doesn't respond to increases in stress as well a muscle would. Bones and tendons can need months or even years to build up the strength to handle the stress of serious running barefoot. People who try this should ease into it slowly. Like over weeks or preferably, months.
I can see how it would be really easy for someone who was actively running when they got the shoes to just go do their normal routine the first day they wore them and utterly destroy something.
I tried to take up running last year. I bought a pair of Vivo Barefoot shoes, and thought they were great. Since I was just starting out I couldn't go more than a few hundred yards without taking breaks to walk. I eventually worked my way up to about 5 miles with a few moderate hills in the route, and never had any trouble with pain or injury.
I never grew to enjoy running however, it was always a chore and while I was doing it my mind was always racing with thoughts of other things I could be getting done if I wasn't running. I didn't feel any better, I didn't have more energy during the day, and I didn't sleep any better, so eventually I stopped.
I still like and wear the shoes, though.
That's pretty much the only thing holding me back from buying them or any of the funky new (curved bottom) shoe ideas, I know I would never wear them.

I'll never buy a "normal" running shoe again.

For regular walking/business shoes give Geox a try. The solid leather insole and lightweight build is amazing. The air transfer through the sole actually works too.
If you mean acceptable in semi-formal or even business casual settings, I would say that will just never happen.
I have been turned away from places for wearing jeans before. I doubt they would allow me in looking like frog man.
It's more "those places" I was talking about. Sure, nobody is going to scoff at what I wear around my condo.
(This could be my foot's fault though, my smallest toe gets scrunched up in the shoe "fingers")
The Merrrell trail shoe someone linked is a good example. I have a pair of pumas that are very similar, though a little more boring.
Edit: From http://en.wikipedia.org/wiki/Fad
>>A fad is any form of behavior that develops among a large population and is collectively followed with enthusiasm for some period, generally as a result of the behavior's being perceived as novel in some way.[1] A fad is said to "catch on" when the number of people adopting it begins to increase rapidly. The behavior will normally fade quickly once the perception of novelty is gone.[1]<<
I'm not sure that we are yet in the "large population" phase even though this is like the third time I've heard about this new footwear.
http://en.wikipedia.org/wiki/Tarahumara_people The word for themselves, Rarámuri, means "runners on foot" or "those who run fast" in their native tongue according to some early ethnographers like Norwegian Carl Lumholtz, though this interpretation has not been fully agreed upon. With widely dispersed settlements, these people developed a tradition of long-distance running up to 120 miles (190 km) in one session, over a period of two days through their homeland of rough canyon country, for intervillage communication and transportation as well as to hunt.
They also have the tendency to eat when hungry, sleep when sleepy (as in, anytime / anywhere) which has threads to other "genius" discussions (lets call being able to run 100's of miles a type of "physical genius" for a thought experiment). I know when I do barefoot walking on a frequent basis my chronic lower back pain starts to dissipate.
Side note: We also aren't naturally meant to sit all day in an office chair, yet...
Note, I'm not necessarily advocating barefoot running. I do run on my forefeet, so I run in Newtons, for now.
Two things though: (1) Heel running is less efficient, results in higher impact forces and leads to more injuries than forefoot running. (2) The only reason most of us heel run is because we started running in sneakers from a young age.
Again, your second link, did you even read it?
