I vastly expanded my available shoe storage space in my closet (not to mention cleaning it up considerably) by installing cedar shoe racks purchased from dann-online.com; very fast shipping by Dann too. Here's the link: http://www.dann-online.com/clothing/...othingmain.htm
They are made by Woodlore (owned by Allen-Edmonds). I bought 4 and stacked them "two and two." My closet now smells like a cedar closet too.
