1. Purchase the appropriate shade of Tarrago shoe creme. (I usually purchase the 3 I think closest, and decide by using some of each on an inconspicuous bit of shoe.)
2. Take a Q-tip and get a goodly amount of shoe creme on it.
it into the scuff!
4. Let dry a bit, and buff it with a horse hair brush.
5. Repeat until the scuff is gone.
I have repaired far, far worse with this method. Shoes that were not only scuffed, but actually gouged. The damaged area can now only be discerned through deliberate and close examination.
I don't know what the current AE product is like, but when I last used it, it didn't have as much pigment and didn't color leather as effectively as some other cremes.
Edit: Looking again at your photo, it appears the hide has a lot of dark patina added over the color of the hide. You may need to replicate this if you want a uniform appearance. I'd try doing so with a small amount of black shoe cream once you get the color restored over the color, applying it very sparsely.
