Here you can see the damage to my shoe. I'm not exactly sure how it happened. What's important is that because it gouged into the leather a simple Saphir Pommadier Cream is not going to do the trick. So, this is where the Saphir Renovating Repair Cream comes into play. The resin-based formula is very simple. Resin + Pigment. It fills any cracks, rebuilds the surface, and will never come off. Once it dries, it will never rub off onto anything.
You apply the Repair Cream with your finger. Massage it into the leather and try to smooth it out. Allow it to dry. Then polish over it with a cream polish to smooth out the surface.
As you can see from the last picture, the Renovating Repair Cream was able to almost completely conceal the damage. For $11, it's cheaper than a pair of shoes and is also EXCELLENT as Edge Dressing.
Hope this helps.
I don't know, that looks like a crack on where the shoe is creasing. I don't think this product could really hold together creacking leather where it flexes. In, my experience once this happens it gradually gets worse. You can condition it and make it much less noticeable with products, but this, I think is here to stay. Regardless, I am ordering some anyway.
I do know that Nick V. At VIP shoe service in Manhattan has taken shoes apart and patched them from the inside. The jobs come out looking really good, however I would imagine it costs a fortune and may change the shape and feel of the shoe if one doesn't have the original last. He said mostly people do it if there shoes have a special meaning to them, like their father's shoes and whatnot.
