For many of us, especially if we live with family, shoes can be a big clutter issue. The entryway of your house becomes a minefield of little shoes to step over, and there never seems to be enough storage to deal with everything. But, if you've got some extra cinder blocks sitting around, you can easily stack them up to create this organizing cubby and immediately straighten up that mudroom for good!
The key here is to make the cinder blocks into functional furniture so that they don't feel like they're taking up too much space. A plank of plywood and a big couch cushion across the top should fix this.
