did yall notice the book called the idiots guide to barefoot running......the picture on the front is of a guy, with an almost straight front leg, with his heel reaching for the ground......barefoot running is a style, as far as i know, not necessarily the relationship to whether there is anything attached to the foot or not.....there are two types of running shoes that barefoot style runners, or as i called it natural style for many many years.....that is the platform style and the support style......i prefer the platform, as taras use, .........no pressure on the sides of the covering....the bottom must be wider than the foot, and it only acts as a platform for the foot to do it's thing.....in the other type, or the so called support type, the whole shoe flexes with the foot....the shoe should , ideally to my mind, do absolutely nothing, except cover the bottom of the foot from rocks, stickers, etc.....thas all...nothing more.....i have about five or six thousand miles on three pairs of propet voyager sandals that i use as a covering.....i have been doing this almost daily since nineteen fifty eight....i saw the horrid shoes with heels come in during the seventies, and i knew from the gitgo that it was wrong, but i was called old fashioned and not up with the new sciences of jogging.....ahem....the worm has finally begun to turn...i am sixty one years old, and still run, all natural style, a minimum of seventy miles per week...no injuries, no knee probs, no nuthin...knock on plastic..its a style, yall.........cheerx, el jefe in austin
