I had a pair of the blue ones; they were the best running shoe I'd ever had. Good support in the heel, excellent for anti-pronation, and one of the best trail running shoes ever. Not sure if it was because of their famous "torsion bar", but they were a bit firm, though. Regardless, my favorite running shoe of all time.
Here is a pic of the originals:
adidas re-released the ZX-8000 with an updated sole (see the blue one). Unfortunately, there is very little arch support. Shame because the shoe is very light and well made. I can't believe how many people comment on it.
Additionally, adidas has updated the series with a new "originals" version called the Mega Torsion RVI available in the original blue and a white/green/red version that is similar to the original. Unfortunately, these are strictly "casual" shoes and I wouldn't bother running in them. That said, also beautifully made.
Have a look at all three
and the different soles
I wish adidas would bring back the original in its true form!
