Lucky the soles are done with a lockstitch. lf one or two stitches are cut in the toe area hopefully the sole will hold until next resole.
Probably right but today the thread used in manufacturing situations in particular is dacron and there is no wax in the word that will hold tight on dacron. Factories don't do hand stitched outsoles and they cannot be bothered to clean up the stitching machines...every day...like was done in the old days when hard, hot melt wax was used. Thus, even though it is a lock stitch, the stitches can slip. Of course, the nail will tend to make up for that slippage but if the stitching does come loose, even a little, dirt and moisture can sometimes get in under the sole.
