I love my Dr. Martens, and I'm sure many of you out there feel the same way.  This product is simply 'the best' for keeping your docs looking new and feeling good.  It helps keep my old English-made shoes and boots in perfect wearably shape after years of use, and gives a significantly longer life to the newer ones not made in England. Worth it.
Frankly, I'd spread it on my bread if I could.
