Kids' Ankle Strap Block Heel Pump

I was so happy to have found these shoes for my granddaughter's First Communion. The heel was the perfect size. I dropped them off at her house. When my daughter opened the bag up (they didn't even come in a shoe box, just a sealed bag), she noticed they had light brown scuffs on them. the soles seemed a little dirty as well. So disappointed. Why would Nordstrom's sell these?
