Hi, A.!
We're only a 4-pair (of-feet) family, but I can imagine the pile of shoes you must have to deal with. We had a lovely boot bench built into our mudroom, but as soon as our kids (and their feet!) got bigger, the boot bench wasn't big enough to hold it all. So, here's what we do.
1. Have a "seasonal" bin in the garage or basement to hold off-season shoes (ie, put the snowboots out there in the summer, put the flipflops out there in the winter). If you don't have that much storage space, another option is to store off-season shoes in boxes under each person's bed.
2. Find a permanent place near where folks enter/exit the house most often (entry way, mudroom, even in the garage near the door into the house) and then buy a set (or two or three in your case!) of stacking bins. You can get these kinds of things at Target, Home Depot, etc. The ones I bought were from HomeDepot -- in the closet organization area. It's basically a frame with metal wire baskets. You can get wheels on the frame, so it can be portable if you'd like to be able to move it around easily. They also come with a plastic topper, which functions as a top shelf to the unit and becomes a handy place to place other things like keys, backpacks, purses, etc. when you're entering/exiting the house. They have worked really well for us. The bins come in various sizes, but I would recommend buying as many of the largest/deepest bins as will fit in a unit, since this will make it easier in winter to store boots, etc. (An alternative to bins is a shoe rack, but I find this option needs a lot more horizontal space that I can spare, and the bin unit uses up less floor space and makes use of the vertical space that I have plenty of.)
3. Assign each person his/her own bin, and be sure to label each bin so everyone knows where his/her shoes go. It will take some training and reminding, but make the rule that when you enter the house, your shoes go into the bin.
This system has helped us not only to conquer the pile of shoes, but also to make it easier for everyone to get ready to leave the house. If you've followed the rules, you always know exactly where your shoes are! If they aren't where they should be, then the naturally occuring consequence of not putting your shoes away properly is that you have to try to find your shoes on your own!
Hope this helps! God bless,
N.
