Dear community, my boots made with greased leather have this and I’ve already greased them yesterday, with this being already present before. Any ideas what is and how to fix it?
Left (I believe) is a discontinued pascal Dr. Martens, right is Solovair derby. I am trying to find something similar to the left one: more streamlined, wraps naturally around the foot whereas the right one expands outwards and looks like a clumpy boat.
