I don't track footwear as a rule, either -- but during my last clothing tracking adventure, a few winters ago, I did track my "indoor shoes" which are the Sarto lug soled loafers in the Finds. I wore them at least 80 times in 4 months!
Because they were until very recently entirely indoor shoes, they are not in the least worn out. However, I have had a need for slip on shoes as I am wearing a sling now, so I'm wearing them outdoors to work.
Those are hard wearing. But I will say this -- in an ideal world, I like to have at least 4 pairs of sandals available in the summer months. And invariably, one pair will be worn out after two summers. Sometimes 2 pairs will have to go. I'm tough on sandals especially.
That is even though I also wear sneakers and stitchlite oxfords in the summer months. I go through those in two seasons, too. t
My winter footwear tends to last longer, partly because I have more variety and change it out more, and partly because the really hard wear is confined to a couple of pairs that are essentially gear-type items -- Blundstones for my walks in the suburbs, my trail runners for jogs or hikes, etc.
All my other boots/ booties are all-day shoes but because I have a range at any time, they last quite a while.
My oldest pair of shoes is the dressy EF pump. I've had them since 2016, I think. But I rarely wear them.
I do duplicate/ stock up on styles that I really love at times before they become unavailable. I have an extra pair of the white Cole Haan oxfords ready to go, an extra pair of the cream Eccos, and an extra pair of the Cole Haan silver sneakers. I get these when I see them on major sale, usually in the off-season.
I usually add 2-3 pair per season each year, plus whatever gear shoes are needed.
