Yes, I am a professional organizer and this is the way I store my shoes. But honestly, it's super efficient and accessible (and they're out of sight) which means no clutter! You may be asking yourself,
how do they not get scuffed? Where are the rest of your shoes? Doesn't that bother you that they're jumbled up in a box?! Ever since I was in High School, I noticed that I could never keep my shoes pristine. I don't know if it's the way I walk or what but my shoes always seemed to get more wear and tear than other folk's shoes (so the extra teeny bit that my shoes might be suffering, I'm ok with). Plus, I only wear about 4-5 pairs of shoes on heavy rotation, so the box is perfect to store my footwear. The remainder of my shoe collection is in my teeny closet (and by teeny, I mean miniature). While my method is unconventional, it works perfectly for me (organizing is not one size fits all:)
you're right, this pic isn't from flickr (it's from this source). i spent all day yesterday creating this exact sort of system for a client (and her 30 + pairs of boots. if you've ever seen the boot boxes from the container store (they're clear but kinda muddy clear). since you can't exactly tell what you're looking at, use a label or better yet--take pics!
