LC (Legit Check) is a term used by sneaker enthusiasts and collectors to verify the authenticity of a sneaker. It is a process of examining various details of a shoe, such as its materials, stitching, branding, and packaging, to ensure that it is an authentic product made by the original manufacturer. Legit Checking a sneaker can be done by comparing it to known authentic versions of the same model or by using online resources, such as forums and databases, that provide information on identifying authentic sneakers. Legit Checking is especially important when buying a sneaker online or from a seller that is not an authorized retailer. Because there are many fake sneakers in the market, the legit check process is a way to make sure the sneaker is not a counterfeit.
