text: Product did not perform as I had hoped. I was looking to repair uneven wear to the heals caused by my favoring the outer edge when I walk. I had applied several layers to build up the heal so the left was even with the right. This didn't work real well; I don't think the product was intended to do this, nor did it claim to- it was just implied. Regardless, I am left with a high quality hiking sandal (Keen's) that remains in perfect condition everywhere except the heel.
