It's a common misfortune...your favorite pair of flip flops break at the stem and they become completely useless. The solution: the flip flop prosthetic. Print it out, push it through the original hole in the rubber sole, and push the remaining stem into the sleeve. You may have to whittle down the tip to fit it into the sleeve, and you may have to cut off the tip of the remaining stem if it raises the straps too high. Secure the stem in the sleeve with some Gorilla Glue and let it sit for at least an hour before using.
