Well, i was just thinking, and it seems as though this is an obvious fact when studying biomechanics.
So they say lots of cushion is bad, but i mean, there are TONS of different materials that companies use for cushioning, and some do use more than others.
I personally run cross country in a pair of New Balance 872's, which a bit towards their high end models (cost about $89.99), and they have been feeling great, no other shoe has ever come close. They're tight and light, and feel like and extension of my foot.
So i was wondering, maybe some comapnies do get it right with a good balance of good material and amount of that material, so i don't think that its fitting that everyone simply jumps on the band wagon of "OMFG SHOES ARE BAD FOR YOU, CUSHIONZ ARE FOR LOOZORZ".
Also, the fact is that there are few places that can be ran barefoot in. Even in our "natural" parks you run the risk of stepping on something hazardous. And things like flats and Vibrams most likely will not give adiquate protection against them.
