The sole of these shoes is made of plastic, not leather like all the other Robeez I've seen, and that makes them quite a bit stiffer than most.  Also, because of the velcro-strap styling, the shoe doesn't fit the same as other Robeez and I find that my daughter can kick these off whereas normal Robeez stay put.

Still, she has gotten many compliments on these shoes, and since she only wears them when she's all dressed up the problems are pretty minor.  I'm glad I got them!
