Thanks, I've actually considered putting in tape on the inside of the shoe to slow down the inevitable. Unfortunately, these are the black/white flyknit trainers that I don't think are being sold anymore/at the moment.
Question: the fabric near the toe of my flyknits is starting to fray. Any suggestions on how to prevent further fraying or even reverse the process (unlikely, I know). If the fraying develops into a hole the shoes probably go in the trash
