14. adidas ZX 8000

Year: 1989

1989's ZX 8000 was the first time a lot of folks bore witness to adidas's Torsion technology (though it debuted on 1988's ZX 5000). It's curious that adidas have a rep for being more restrained than some rival brands - they're pioneers when it comes to high-concept applications. The 8000 took the ZX blueprint and redefined it with that Unity heel counter and the Torsion bar application. No good for the wide feet out there, but those who could wear a pair comfortably benefited from that aqua and yellow color combination too. The ZX 9000 is also excellent. Built for cushioning, this put adidas back in the race during an era of ludicrous gimmickry (discs on tongues, catapult heels and reactive liquids are a fail), but this model has aged well.
