I reuse them to organize dressers and closets, otherwise I recycle them
for my nice shoes, I either keep the boxes, or find a fancy box to store them in
for every other shoe, no lol
I throw them out, I use my shoes I buy so I don’t really need them. I also have a shoe hanger on my closet door so I put them there too
I have a collection so I keep them and organize them by brand and number
