I purchased a Mainstays 10 Tier 60 Pair Metal and Mesh Rolling Shoe Rack from Walmart but the wheels were small and immediately broke when loaded with heavy Mens shoes. Realizing that this probably needs a little improvement, I designed an adapter that uses my leftover office chair wheels that were upgraded as the main support. These adapters fit the metal tubes and allow you to use standard office chair wheels which are much more durable.
