Working for a shoe store I have come across many people who wear the wrong type of shoe for the activity they are doing. Many people have shoes for different activities. For example, an athletic sneaker, a comfort sneaker, and even a sneaker for fashion. I always come across people who think they bought a a running sneaker but their feet have started to hurt. When I look at the shoe they bought it seems they have bought a shoe that was entirely for a different activity. They bought a fashion sneaker. So the question here is, how can you ultimately tell the difference?
