Abstract: A footwear measuring apparatus includes a body, a plurality of probes, one or more measurement devices and at least one calibration sensor. The plurality of probes are configured to extend from the body. The measurement devices are configured to measure distances that the plurality of probes extend from the body, wherein the distances indicate fit parameters of footwear. The at least one calibration sensor is configured to determine if the footwear measuring apparatus is properly positioned inside of the footwear for measuring.

Abstract: A computing device executing a footwear sizing module receives first fit parameters of a footwear having a first footwear size. The computing device computes additional fit parameters of additional footwear sizes of the footwear based on the first fit parameters. The computing device stores the first fit parameters and the additional fit parameters of the footwear in a data store.
