What you need:
2 - command strips with hooks per shelf
1 - 1/2" dowel rod about 24" long (depending on the width of your shoe rack) per shelf
Step 1: Bend the Command Strip Hooks
Step 2: Attach Command Strips
The next thing I did was install the command strips to both sides of the shoe rack. Make sure both strips are placed at the same height and distance from the back of the shoe rack.
The command strips have a one hour cure time, so during that time I built the rods.
Step 3: Make the Dowel Rods
Measure the distance between the pads on the command strips. I have this labeled as "Pad Distance" in my picture. Cut the dowels about a quarter inch shorter than the measured distance to give you a generous tolerance.
Next measure the distance between the hooks on the command strips. This is labeled "Hook Distance". This is the distance you need to keep between the center point of the mounting holes in the dowel rods. Try to keep equal distances on each end of the dowel rod past the mounting holes.
The approximate width of the hooks is 3/16" so I used a 1/4" drill bit for the holes.
Step 4: Install Dowels
By this time the adhesive on the command strips should have cured.
Place the dowels in the rack so the hooks are placed in the holes, and the dowel rod is supported on both ends.
Now you can put all sorts of flat bottomed shoes of the racks. Once you are ready to move out, you can just remove the command strips without putting any extra holes in anything.
