Whether you should use hand-me-down shoes depends on the age of your child. Socks and booties passed from one infant to the next are no problem, and likely the same goes for those soft leather models that they wear when crawling around in the later months. The main thing to watch for during this time is that the socks, bootie, or shoes do not constrict the foot in any way.
However, once your little one begins standing and walking, the requirements are different. Even small bodies put more weight on certain parts of the foot than others, so the shoes become molded to the foot shape. Putting them on another child could mean friction at certain spots that could cause blisters. That said, pairs for special occasions that get little wear could probably be used for the next child, too.
