i was very challenged to find a suitable running shoe,
i landed on the front of the foot, then heel, then lifted off the front part of the foot.
the adidas 72 was the best, then the sl 76 came out and it was more than terrible.
since i would find a good shoe, and within 2 years they "upgraded" it, where they changed back to a clunker overpadded, which causes knee and shin issues, which every coach knows about, except the new design team did not know anything about shoes, and god knows what happened to their former good team, that got it right.
this is the experience,
a good shoe is discontinued and the next generation is crap.
for all their warts, al salazar, gordon pirie, percy cerutti, victor conte, and many other world class sports medicine pros (from premier sports leagues), they know the biomechanics and principles in the gate, foot plant, transfer of momentum, and these types are the ones that can contribute.
big corp on the other hand, in their weird power games and hubris, will fire the good guys, and bring in phonies.
this is called the theory of de-evolution, where, despite all the money and technology in the world, things go backwards.
this is your world today, top to bottom
it is counterintuitive, but fact. beyond repute.
at one time, i went with basketball shoes that offered great support, and without padding that messes up your stride.
letsrun could do us a favor and do a biomechanics study of at least a handful of shoes, and lend a verdict, and also red flag model changes that are obviously garbage.
