Shoe Goo is great. It dries really solid and hard-wearing. You have to put it on in layers and build it up as each layer dries. I've saved a pair of shoes I love that had really worn heels and have been using them for two years since. I've just retreated the heels and hope to get another two years. Highly recommend.
She's totally lying I've used that stuff countless times on my boots and my soles when they come apart this stuff lasts about a week and then falls apart over and over again!!!!
