I don't know how other reviewers were able to get 45 pairs of shoes on here.  My daughter wears a size 6 narrow and 3 pairs of her shoes will not fit on one row.  This will only hold 24 pairs for us.  Even the picture on the box doesn't show 3 pairs in one row.  Not happy with the deceptive ad.

This unit was easy to put together and seems to be pretty sturdy.  If you only need to store 24 pairs of shoes this unit will serve you well.
