^ I did a coat of Obenauf's after about 6 months of use thinking I'd let the leather get a little broken in to better absorb it, but I probably should have done it right away, and more regularly. I don't have as pronounced toe-scuff/color change as boibleu22 but it seems that's the direction it's headed. i think the eary and often approach helps to mitigate this, but heavy use in wet/snowy weather probably leads to that over time.
I dont think applying obeanauf sooner will help. I tried obenauf on my brand new pair, on a tiny spot inside the tongue area. It doesnt get absorbed at all and leaves a shiny finish.
I believe its due to the leather still new with natural oil and stuff. The leather was treated in the tannery so maybe its good to roll without much additional care.
I will again, try to apply obenauf on my GT later to see if it gets absored.
