Patent ID: 8751320

Claim:
A method comprising: receiving, by a computing device executing a footwear sizing module, first fit parameters of a footwear having a first footwear size; computing, by the computing device, additional fit parameters of additional footwear sizes of the footwear based on the first fit parameters, wherein computing the additional fit parameters for an additional footwear size comprises: computing a first internal girth of the first footwear size based on a first internal height of the footwear and a first internal width of the footwear included in the first fit parameters; determining an additional internal girth for the additional footwear size based on adjusting the first internal girth by a specified amount, wherein the specified amount is based on a difference between the first footwear size and the additional footwear size; and computing an additional internal height of the footwear and an additional internal width of the footwear for the additional footwear size based on the additional internal girth; and storing the first fit parameters and the additional fit parameters of the footwear in a data store.
