pumps

I have been searching for the perfect pair of red pumps. I have fallen in love with several pairs...However I haven't been abloe to get them because I am doomed with a narrow heel! I do not want anything too high or pointy...just a basic plain pump. Does anyone know where to find pumps that work for people with skinny heels? Or if you have any alternatives that would be great! ooh the only other thing is...the shoes have to have a back. (I want to wear them to school.) thanx
