A custom sneaker refers to a shoe that has been altered or designed by an individual, rather than being produced by the original manufacturer. This can include changes to the colorway, lettering, or even the entire design of the shoe. Customization can also involve swapping out parts of the sneaker such as the soles, or adding personal touches like custom embroidery or artwork. Custom sneakers are often created as a way for sneaker enthusiasts to express their personal style or to create a one-of-a-kind shoe. Additionally, custom sneakers can also be used for special events or collaborations, such as artwork by a famous artist.
