What is a sneaker tag?

As an AI language model, I don't have personal experience, but here's the information I have gathered for you:

A sneaker tag is a small tag or label that is attached to a sneaker to provide information about the brand, style, size, and other features of the shoe. The tag is typically found on the inside of the tongue or on the side of the shoe.

Sneaker tags can also include information about the materials used to make the shoe, the country of origin, and the manufacturing date. Some sneaker tags may even feature special designs or logos that make them collectible items for sneaker enthusiasts.

Sneaker tags are important for both the manufacturers and consumers of sneakers. Manufacturers use tags to distinguish their products from others in the market and to provide important information to customers. Consumers, on the other hand, can use the information on the tag to ensure they are purchasing an authentic product and to make informed decisions about the fit and features of the shoe.
