For being "unorganized" (ie not using closets) this looks pretty darn organized! ... we just toss them into the closet into the huge shoe pile abyss... there may or may not be be a lost cat in there.
Ha, storing shoes are definitely a problem. We have far too many all over our house. Sizes of feet are UK8 to UK14 - so they are an obstacle. Better not let the 'elf and safety inspectors in to your house though - there looks to be a trip hazard!
