So I have a confession... I don't like to wear shoes. I even kick them off at my desk at work. The price I pay for comfort is grungy insoles. I'm gonna spare you the before pictures and get straight to the pretty after shots:
This was so simple, you're gonna want to do it to all your shoes! You just need some craft foam, (they sell sheets of it with a sticky side in packs of 18 at JoAnns and Michaels), a pair of pinking shears, some fabric scraps, and an insole. I smoothed out my fabric scraps onto the sticky side of the craft foam, pulled an insole out of an old pair of tennis shoes & used it as a template to cut the fabric covered craft foam with pinking shears.
