So, I got a pair of White's and I'm immensely pleased. However, about a month in I got a scuff on the heel (see pic.) I'm just wondering what the best way of taking care of this is. I tried Obenaufs, but it doesn't darken it that much. Thoughts? (And thanks in advance.)
Fixing scuff on my White's boots
I would leave it. These are a workboot aesthetic, so embracing scuffs/scrapes/dings will both make the boot better looking and allow you to wear them without worrying.
Beyond that, putting Obenauf's on is *not* want you want to do, as it's created for a very different purpose (waterproofing), and it can dull the leather. Obenauf's can be a great product when used in the right application (boots that will see a *lot* of water and snow), but given your stance on this scuff, I would imagine Obenauf's is not appropriate for your boots.
Lastly, if you're set on trying to hide it, you'll have to tell us what leather your boots are made from.
