"As for being "able to tolerate it if you are engaged in a serious running program"…Does Alan Webb train serious enough? He incorporates barefoot running. As does Kara Goucher. And Alberto Salazar. And Tony Krupicka…."
OK, a few more, but still a small minority.
"And what of their form? Do they plod along heelstriking like so many of the recreational runners out there…or are they on their toes, posture vertical, taking quick, smooth, light strides…
…wait a minute, that's how I learned to run barefoot."
Definitely, all the really fast runners are forefoot strikers. But I fail to see what that has to do with shoes.
A good runner will do that with any shoe.
"I'd say Haile's pretty "serious".
Me too. He's one of my heroes. And now he wears shoes. Does he train barefoot? I doubt it.
"It appears the majority of runners with hi-tech shoes don't tolerate "serious" training too well as it is…"
No argument there. And, don't get me wrong, Craig, I am not a fan of squishy hi tech shoes. When I started running, I used Nike Daybreaks, a decidedly low tech shoe, for training and racing. When they were discontinued I used ASICS DS Trainers for mileage and Terras for races. Light and simple. I also watched a lot of people with the kind of shoes you refer to and had pretty much the same reaction you express. During the early 80's I was around a lot of really good runners, a couple of whom went to the Olympic Trials in 1980, and I never saw anyone run barefoot, ever, nor did any of them ever mention it. They did, however, wear very light shoes. Anecdotal, to be sure, but I think it reflected the general attitude of the times.
I remain to be convinced that things have changed much since. Again, I would be genuinely interested in your feedback in a few months or even a year as to how you fare running barefoot.
