Between my husband and I, we routinely have 10 pair of footwear by the front door. In Hawaii, its tradition that you remove your shoes at the door. Unfortunately for us, our condo doesn't have much room by the door. As such, there would often be a pile of footwear as you entered the unit, which is the kitchen. I have tried various shoe organizers over the years, and none really fit the bill, or the space we had. So I built one myself.
Its a pretty basic box, with 1 fixed shelf. All joined with my Kreg jig (of course). I also attached some casters on the bottom to make it easier to move out of the way if needed. After assembling and painting, I picked up some moulding and added it to the bottom, which helped to hide the casters. Then I used some old liquid nail/caulk I had to fill in the holes.
