I absolutely LOVE the Grid closet system - they've made a huge difference is our closets & how efficient they are.  You're able to create your own design, so you can tailor to your needs & maximize the space you have.  I bought extra shelves for this unit, so it's devoted to shoes only.  These mount/hang from the walls, so there's nothing on the floor - another plus for me.  I've already suggested these to another friend.  5 Stars!!
