... I ruined one of my favorite pairs of shoes .

I locked myself out a few days ago right as I was supposed to be heading to school.  We have a sliding glass door that doesn't lock properly, so I popped it open and thought I could get the stick out of the door by reaching in with some sort of garden tool.  I was incorrect.  So I ended up being late to my first day of class, I have bruises on my forearms that make my husband look terribly abusive, and I ruined the toes of my favorite shoes as I was kneeling on the pavement.

The leather is very soft, and I scratched it down to the material on the toes .  I think they're beyond repair, so I need to replace them.  I might not choose shoes like this normally, but need something that's suitable for school (see criteria below) and these are perfect - they really just look like simple ballet flats under jeans.

Can you help me?  I would love to find the same shoes again, but can't find them in my size (6) for a decent price, since they usually run $90-ish.  I need something similar - closed toe (science lab rules), low wedge, relatively comfortable since I'll be standing in them alot, cheap as possible.  Please ?
