It depends on how you define "rotation".

I own about 35 pairs of sneakers (I'm a "sneakerhead" but picky about what I buy and I also periodically sell/donate pairs) and I will wear all of them but how frequently definitely depends on the pair.

I consider any shoe I will wear as part of my rotation...but some of my pairs I probably wear twice a year max.

I also have two pairs of "dress" shoes for work - a black pair and a brown pair. I wear both weekly just depending on what shirt I'm wearing...usually the black pair twice a week and the brown the other 3 days.

That's about it for my shoe rotation.

edit re: the wife - my wife doesn't have a problem w/ it because i use my side hustle money to cop. also, she's a bit of a shoe fan herself so i usually cop her a pair here and there.
