2. SL 72
Year Introduced: 1972
No company capitalized more from Olympic years than adidas. The SL was introduced for Munich in 1972 as an all-around training shoe - a popular category even 15 years before Nike 'invented' cross-training - and the sleek shoe found its way to many podiums in the same role the Nike Flyknit played this past Games. And like the Flyknit, the nylon and suede SL performed as good as it looked.
