Growing up we called all athletic shoes "tennis shoes." We all played tennis, but it was just one in the myriad sports I participated in during my youth. Since then I have learned that not all sneakers are meant for every activity. Currently I have two pairs of running shoes in rotation — one on the way out and one I am breaking in. I wear my Nike Zooms for strength training. I have a pair of cycling shoes that clip into my pedals.That's four pairs of athletic shoes that I own and use regularly. How about you?
