Use a needle and plain thread to tack the wire down along the inside of the shoe. Knot the thread and cut off the excess.
When this guide was written, we had an EL inverter stocked that could handle driving a 1.5" round EL panel, our current coin inverter cannot, you can still build this project but please use our 1xAAA inverter https://www.adafruit.com/product/1349
Use a small piece of fabric to secure the inverter along its edges. Pin in place and sew along pin lines by hand with a running stitch. Make the fabric snug around the inverter so it doesn't slip out the bottom! However you should still be able to slide the inverter up for replacing the battery.

Secure the wire leading from the inverter down the tongue of the shoe in the same manner as you did the wire from the EL panel. Plug the cables together and tuck the junction between the laces and check for a comfortable fit.

A 1.5" circle of EL panel is about as much as this tiny coincell inverter can power at once, and the battery life is about an hour before noticeable dimming. You can increase battery life by upgrading to the 1xAAA inverter (which is only marginally bigger but a little heavier) or try making cutouts where the EL panel is not used (less panel = longer glowing).
