I do need to simplify my shoe life. I have an "in season" closet and a "not in season" closet and switch them every six months. I don't particularly love shoes, but when I buy shoes it's mostly the expensive ones that last forever. So I tend to build up a stash.
Two years ago I rigged up a string and hook system on the back of my closet wall which allowed me to hang up 30 pairs of shoes, giving me more floor space.
I am now out of floor space. It's possible I have a problem (but my step mom gives me like 20 pairs of shoes per year, too, so she isn't helping my problem!)
