Right then, this is Proper Boot Dubbin from England, where they know a thing or two about preserving leather in the face of damp weather and dank conditions. Consisting of all natural waxes and oils, this product is aptly labeled ‘food’ as it replaces the waxes and oils found in leather that are depleted by the tanning process itself, as well as by general wear and climate. In production for over 100 years, it was used by Sir Edmund Hilary on all his Everest assaults. We know it works quite well on riding boots. The black is especially beneficial as it fills chips and cracks on black leather. Specify black or natural.
