It has got nothing to do with oils. This all happens on the vamps as well as the captoe and heels which never see conditioner of any kind. It's water getting caught in the wax along with whatever else is in the water. This doesn't happen with calf and is endemic to shell for reasons unknown. The leather doctor stuff I use is emulsified and the coconut oil in Glens stuff is raw so I get the best of both (and the worst of both). I've tried his waterproof stuff on my shell shoes. Completely stripped them down applied it liberally and while water did seem to bead a bit more it still left the marks. I've exchanged some emails with him about it. I am using it on my rainy day beater shoes and while it does help wick moisture you're still stuck with having to clean the city streets off of them that gets kicked up onto the uppers, which honestly imo, is the problem with wearing leather shoes in the rain, not so much the water itself.
For the bold section:- hot-stuffed, jack-glazed muscle sheath is the prime reason, and somehow the stationary moisture in shell isn't enough.
Are the markings really that hard to remove, even when the waterproofing cream was applied? And as of what was in rain's water, I can name acid for one.
Other than that, I am kind of speechless. Do you know if there is a specific type of shell St Crispin used? I know from Horween, but I wonder if the inspection process of the hide - i.e. the criteria set - has got something related.
I've been known as an idiot who used grease and wax based dressings on shells and I haven't seen a spot so far. I know rain water and puddles can make shell looking ugly, but throughout walking under the rain and cleaning the shell with water, even, I haven't yet to experience any kind of nasty spotting on the surface.
