In hot weather and after a long walk in the rain, picture taking off your sneakers to dry, then wear them again. Now look at these sneakers, rubbed in my foot sweat buildup after months and months of walking. Look at how dirty they're inside. Put your nose a little closer. These sneakers look so misused you could almost smell them. Mmmm, take another whiff of that delicious, vinegry dirty sock, feet and sneaker aroma!
