Barefoot vs. VFF
VFF are shoes. In fact, they are shoes with the same thickness of sole and lack of support structure as the training and racing flats we wore back in the 70's. Nothing new there. (what is new is the toes, which I'll get into later) We ran looong distances and fast races in shoes very similar to VFF and Newtons, etc.
Big wedge heels and complex support structures have been the fashion for 30 years or so. I think we're seeing a backlash against that now.
Here's my opinion why: it is very hard to run in poor posture in training flats.
(Mind you, I think everything wrong with the universe is due to poor posture.)
Let me start off by throwing a metaphor into the mix.
Pretend we've got a teenager who slouches. Are we immediately going to give him pain drugs and put him in a brace and run tape along his extensor muscles and make him sit in a high-backed ergonomic chair? No, we're gonna yell at him to sit up straight! If he can sit up straight on his own, then we know it's just a sloppy posture problem, and we nag him to change his habits. If we make him sit on a stool in good posture, it's hard work and he can't do it for long, but it's good training. If we put him on a plane for Australia, are we gonna make him sit on a stool? Heck no, we're gonna put him in a nice ergonomic chair! Sitting on a stool in good posture for that long would be agony.
However, if our teenager simply cannot sit up straight on his own are we gonna put him on a stool? No. We're going to give him an ergonomic chair and we're going to investigate why he can't sit himself up straight and we're going to address the problem.
There is a time for the stool, and there's a time for the ergonomic chair.
