6 months in I think... only had a few days off in that time. Hundred of miles logged so far. The only real sign of wear is the heel is being ground down a bit due to walking 5ish miles a day. I usually use Obenaufs LP but Skidmores is made just up the road from me so I gave it a go. It darkened them a tad but still not as dark as my walnut Rangers. I suspect like Obenaufs, this will lessen over the next month or so.
