I rebuild the heels of my athletic shoes with Shoe Goo as needed rather than buying new shoes because of that particular wear. The material in the tube stays fluid for a long time when the cap is firmly replaced, the remaining Goo is squeezed toward the dispenser end, and then the empty part of the tube is carefully rolled up behind it. This works so well that I didn't have to open the tube I just bought!
Shoe Goo helps you tennis toe draggers shoes last a little longer/ With tennis shoes costing about $100 plus you may get a little more miles on your shoes and save a little money over the long haul. Keep hacking!
I followed the directions in an attempt to repair the rubber bottom/sole of my tennis shoe. As soon as I lifted the weight of off the shoe after leaving the glue to adhere for 24 hours, it came undone immediately. Tried the product on a second shoe with the same result.
