An anti-counterfeiting serialization method. The method can include receiving an input serial number, locating a seed character at a predetermined position in the input serial number, determining, based on the seed character, a first output position for an incrementing character of the input serial number, determining, based on the incrementing character, at least one second output position for at least one remaining character of the input serial number, and generating an output serial number having the incrementing character in the first output position and at least one remaining character in the at least one second output position.

Provided is, among other things, a shoe having a sole that includes multiple layers and an upper attached to and extending above the sole. In addition, the shoe includes a tab having: (1) a first portion, located between adjacent layers of the sole and thus hidden from view, that is imprinted with identification information pertaining to the shoe and (2) a second portion that is visible during ordinary use of the shoe.
