I noticed on my shell patriots that the stitching on the sole is coming unraveled in one place where the leather is wore down. It makes sense that this will eventually happen on all AE shoes with an open grove for the stitching but it alarms me a bit. Should I be concerned at all? I'm thinking about going and getting a topy put on them. The shoes are only a few months old and have been worn less than 20 times.
