From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
A useful Way to make Boots Waterproof.
Take four ounces of sweet olive oil, sixteen ounces of tallow, four ounces of turpentine, eight ounces of common lard, and four ounces of new yellow bees'-wax, mix together, and after drying the boots, no matter what kind of leather they may be, well dried and slowly warmed, grease them with this mixture thoroughly, and no water will penetrate through them, and the feet will remain dry therein.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
