Mine got them for their birthdays at 4 and 2 this summer; they are the kind that fit strapped over their shoes. The thing I would mention is if your kids have wide feet/wide shoes, they may not work for them. My kids' shoes are too wide to fit in the skates, so they have to try to use them without shoes on. THey are meant to be used with shoes on, so really don't work too well for us.
