I was reading a thread elsewhere on "letsrun" where some old timers referred to a blue and white striped Onitsuka Tiger racing flat. Perhaps the 'Marathon'?
Does anyone know or recall what those shoes weighed? The last guy I saw wearing a pair was Johnny Kelly when he ran at Boston a few years back. I recall he has two Massachusetts State Policemen running with him to more or less protect him that day from over-exhuberant fellow runners/well-wishers. He may have in fact only run the last 5K that year. I remember it was drizzling or misting that day.
As an old-timer, I don't recall us ever weighing our shoes per se, but wearing the right shoes was a big deal. In fact, at one dual meet, I recall our track coach yelling & growling at a sophomore for running a two-mile race in his 'training shoes' on a cinder/dirt track.
Those 'training shoes' are more or less what the Nike Cortez casual shoe is today!
