Sizing for Fast Fit®

It's easy to size your child for Fast Fit products! We have a few options:

Fast Fit Sizing Jig

  • Request a paper sizing jig to be mailed to you at no charge by calling us at 800.848.7332.

Trace the foot

  • Stand the child on a piece of paper (in weight bearing) and trace the feet. Then mail (don't scan or fax) that tracing to us.
  • Measure the length of the traced foot (adding 1/4 to 1/2 in. for growth) and order that size.

Bug sizing

  • For the Bug, simply measure the insole of the child's well-fitting shoe, and order that size in inches. Watch this quick video for instructions.
