My little boy LOVES these boots bc of the dinos.  But after wearing them only a few times, both boots had cracks/slits above the green dino. on the outside ankle.  It was kind of a pain dealing with it, but I finally got someone at amazon who sent me a replacement pair- though that pair was $5 cheaper then the original $30.99 I paid.  Anyway, I hope this new pair lasts longer, but they're obviously cheaply made.  The next time he needs boots, we will be buying a different brand- something more expensive.  We've been saving his shoes for his younger brother, but it doesn't look like these boots are made to last.
