49. Mizuno MZ-84
Mizuno's branding was poor, but their shoes were insanely advanced in the quest for peak performance. The Cassette Insole system was the stuff of techy fantasies, coming with a duo of insoles that had a variety of separate forefoot and heel pads that clipped in, complete with an elaborate chart to document the benefits. Tailored to your weight, the shock absorbing properties were a bespoke solution, and on the MZ-84, the pronation bar and resilient midsole completed a sensible-looking shoe that concealed its insanity well. The adidas Micropacer's stopwatch and PUMA's RS Computer Shoe went crazy on the gimmicks, but this one knew to keep the funny stuff hidden.
