The Songmics 4-Tier 20 Pair Shoe Rack is carefully designed and finely crafted with selected iron poles and plastic connectors. This 4-Tier 20 Pair Shoe Rack is of simple structure and yet practical and functional. The shipping box only contains 3 kinds of iron poles and 2 kinds of plastic connectors. Keep your shoes well organized instead of scattering them around and making yourself embarrassed when having visitors. It's a great storage rack for your doorway, entryway and closet. You may order 2 units and stack them to get an 8 tiers shoe rack or customize them into other layer quantities you need. Consider a larger option if you’re looking to store large shoes (Men’s Size 13 or over). Check out the You Might Also Need section for an alternative.
