This is a fairly faithful replacement for a CROCS-brand strap. The model is fully parametric and may be resized to accommodate your child's shoe. Just adjust the CenterToCenter parameter to match the distance you measure between the approximate center of each rivet hole when the strap is laid flat.

The STL provided and default parameters for the Fusion 360 file are for son who was 4-years old at the time. I believe they are US size 5T.

There is a good chance this model could be used as is for adult CROCS too.

Print Parameters
