Nike shoes not of good quality anymore

I bought a pair of white Nike for my daughter before school started. We are only in the second month of school and this shoe's glue has worn off now he shoe is open where the glue is supposed to be. I pay alot of money so that the shoe can last for the year. I might as well have bought cheaper shoes. Wat am I supposed to do now with a Nike that my daughter can't wear to school anymore?
