My daughter wore these shoes for approx 4 hrs the first day and the stitching that holds the sole to the front of the shoe came loose.  This stitching was a major consideration for buying this particular shoe.  My kids, everyone else's I'm sure, drag the toe of their shoes whether crawling or just playing, so the stitching seemed that it would prevent the sole from seperating from the upper.  The stitching can't stop this though if the first wearing breaks the stitch.
