I took the shoes back this morning and told them what happened. All she did was thank me for bringing them back and that was that. I asked her if I could leave my contact information just in case her manager had any questions, or there was any other problem.
Looks like I lost a night's sleep over nothing. I will definately be more careful and learn to pay attention to what I'm doing next time I go shopping with kids in tow. Thanks for your replies.
