Easy to assemble, this over-the-door shoe rack can also be easily hung on a wall (which I did inside my closet).  As many reviewers said, trying to fit 3 pairs across each section is not easy (maybe for children's shoes), but I wear a size 10 woman's shoe and I was able to fit all my shoes, sneakers, heels and booties on this rack (2 pairs on each section).  That's 24 pairs of footwear, more than I was able to fit on any other type of 'hanging' shoe rack.  I definitely recommend!
