Shoe Goo 3.7 oz. Black Shoe Repair ....I was skeptical as to how this product would work, but after reading good reviews, I decided to try it as I had nothing to lose but a little money. I have a really nice pair of knee high black boots that I've had for years. They still look like new, except for the sole which developed horrible cracks and pieces of the sole breaking off. I used the black Shoe Goo on them and even put the pieces back on that had broken off. Well, let me tell you...this stuff is AMAZING!! It was awesome that it came in black because the soles of the boots are black! It worked and I didn't have to throw my boots in the trash!!! I recommend it!!
