I'm not married, but when I was in college I shared an apartment with three different guys...uh...all friends.
One of them put shelves four rows of shelves, on three walls of his room. Each shelf was about 6 feet long, so that is 72 feet of space. The shelves were for the sole purpose (pardon the pun) of storing his shoes. I think he had about 40 pairs probably more.
One of the other guys had a shoe shelf in his closet, and all of the others laid out neatly on the floor of his closet, he had about as many.
The third roomie had I think 3 pairs, tennies, flipflops and dress shoes.
Well, one night I came home from a late class, walked into the living room which was a very large room and found to my amazement the entire room was covered in shoes. Men's shoes, of all types and colors. Apparently, my two (to quote Brendajos) shoe hoe roomies had been drinking and decided to see who had the most shoes. Rather than counting, they decided to split up the living room one side for one, the other side for the other, and they laid out ALL of their shoes. Now this was about 4 or 5 years ago, but I think in all there were about 90 pairs of mens size 13 and 14 shoes in the living room (they were both tall basketball players).....needless to say, there are plenty of men out there of all ages with a love of shoes. All of their shoes were basketball shoes, neither of them had one pair of dress shoes or flipflops....let me tell you, it was quite a sight and one I'm not soon to forget. Especially seeing I have probably 6 pairs of shoes, two that I wear regularly.
