I ordered a pair of Chruch's Consuls from Herring's (very speedy service, by the way), and upon initial inspection, I noticed a strange crease that appears on the inside of the cap stitching of the left shoe when I walk. The other shoe creases much more neatly, and without affecting the cap of the shoe.
The shoes fit well, so that shouldn't be the issue.
Edit: It seems I was wrong and that shoes don't fit well, which resulted in the unusual creasing.
