Year Introduced: 1984

It was the year of Orwell and Macintosh, a perfect time for the world's first computer-assisted sneaker. The adidas Micro Pacer had a futuristic look to match its performance, as its silver upper contained an advanced (for the time) microprocessor which measured everything from distance travelled to calories burned. It's since returned to the market several times as a curiosity, most recently as a Size? exclusive.
