One of the most important things for children beginning to skate is to make sure their skates fit. A popular complaint for kids is that their feet hurt which could be caused by skates that don't fit or muscles that need to be built. While standing, a child should be able to brush their big toe against the front of the boot. If the toe is jammed against the front, the boot is too small, and if they can't reach the front of the skate no matter how hard they try, the boot is too big. Both problems will hurt their balance and hinder their development.
