sneakerfetish
When someone has a fetish for sneakers. This can be for clean sneakers or filthy sneakers that have mud or has just been used so much that they stink. Certain aspects of a sneaker can be the subject in why someone has a sneakerfetish such as the airbubbles on Nike Airmax's or the heavily worn insoles of a sneaker.
