Perfect for childrens' shoes.  If you're an adult forget it.  Tried to fit size 7 adult shoes on upper tier and unable to close cabinet.   You can store shoes slantways but then you may be restricted to 6 pairs.
At least the returns process was simple and supportive.  It still cost us several hours assembling and disassembling this item. 
DONT BUY  (unless you have very small feet).
