Just in case you run in the pitch black like I do most of the time, I found and old pair of my kid's light-up slippers in the trash (they are the Buzz Lightyear models from any Walmart or Target) and ripped the LED lighting system out of them and hot-glued them to my running shoes--now, with every step at night, they do a crazy light show for the oncoming traffic.
Step 1: Buy the Materials
Buy the slippers at Walmart or Target. Better yet, your kid may be throwing an old pair away! When you have the slippers, gently slice into them with a razor blade and remove the LED lighting system carefully. Be careful not to slice through the wiring. They were hot-glued into place, so, I had to rip them out forcefully. You will need a hot-glue gun or Liquid Nails to reattach them back to your running shoes.
Step 2: Attach the Lighting
Simply hot glue gun the LED lighting octopus (it really looks like an octopus when you get it out of the slipper) onto the tounge of the shoe, running it down and out to the top of the shoe. You can glue them anyway you like. I mounted one of mine on the top of the tounge, and down each side of the shoe. I glued the sensor switch onto the tounge, which seems to work great. When you are done, let them dry for a few hours and then go test them out!
