Seen your kiddie converse on PP. They look so cute and I imagine do work better..the adult ones cover more of the metal bit..that how hex cheats with getting up :p
And Joe...the tire socks toddy gave a link to are not the coloured (white,green,black,pink). I have not tried the ones shown in the links but the coloured ones are the best I have ever used. I totally recommend them. They give real good grip and are very hard wearing.
