I noticed that my C&J Whitehalls are showing a bit of wear on the sole near the toe. The sole has worn down just a bit and the stitches are peeking through. Should I immediately have them resoled, or is this just part of natural wear and something I can take care of in time? One thing I've done with cheaper shoes is have a cobbler put a thin layer on the sole when this starts happeneing. But have never been in this position with high-end shoes. Anyone?
