Haha, I thought it was only me loving to smell trainers. By the way, from where do you buy them? I'm used to smelling only mine but got bored quickly. You realize that smell most of the time is pretty the same. I like my smell, but I can't even imagine the touch of variety from other's shoes. Especially from random people, like you do. The only other's smell I tasted was of London's mistress, you can check her here
