Query: Shoes slip off....

I'm asking myself why I put up with this shoe rack for over 3 years now. We're using it for our daughter's shoes. We've been frustrated with it since day 1. The racks slope too much; few of her shoes will stay on it. If you use this rack only for shoes that have a heel, even a slight heel, you'll be happier with it.
