The best skates for kids are ones that the kid likes (not the parent!) The first barrier for kids learning how to skate is pure enjoyment. If the kid likes the look of the skates, or thinks they look cool, they are more likely to keep at it.
Finding a size to fit kids can be difficult, the best option is to go for an adjustable version that will grow with the child and last them longer. These will generally have a larger wheel-base and a wider footprint, making it easier to balance.
