KangaROOS are an American brand of sneaker originally produced from 1979 through the 1980s, with a later revival that continues in present. They were notable for having a small zippered pocket on the side of the shoe, large enough for a small amount of loose change, keys, or more recently, condoms.
KangaROOS were designed by American architect and jogging enthusiast Bob Gamm. Gamm was a running enthusiast who would go ten kilometers a day, but preferred light athletic clothes without pockets. He designed the sneakers for his own personal use as a place to store his keys and money, then marketed them effectively. His marketing design was successful, leading to sales in excess of 700,000 pairs a month by the early 1980s (via wikipedia).
