Minimally-Functional Shoe Hook

I wanted to keep our outdoor shoes off the ground and oriented so that, hopefully, fewer things would end up inside them (cobwebs, leaves, spiders). This is the bare minimum that accomplishes that task. Anyone can build a bridge that stands up, but it takes an engineer to build a bridge that will just barely stand up. I am not an engineer, but I think this is a hook that just barely holds my shoes.

The tolerances between the cleat and the hook could be tighter, probably. The hook itself could be, perhaps, larger. It fits the cleat well enough and (barely) serves our purposes as is, though, so I declared the design "finished".
