I have definitely eased up on my shoes over the years as far as the wear. I don't necessarily break fewer shoes than I did before, but the heel tips do not wear out nearly as fast as they used to. It's not that I walk timidly, I just walk more gently, as you suggest. Specifically, I don't do a hard heel strike anymore, and a lot of that has to do with ankle flexibility that I've developed over the last decade. Nevertheless, I basically have only one pair of stilettos that I wear for occasional walking, and I have posted a picture here. They actually measure 120 mm high, but are the most walkable shoes I have at that height. I use them as practice shoes to help me walk better in my higher shoes. I also wore them to church last week in deference to Pride Month. Unfortunately, the sanctuary was decorated weirdly for vacation bible school, and nobody could see my feet. Anyhow, I got 9 miles out of the stock heel tips, and over 16 out of the replacements. I'm on 30 miles total for those shoes. To put that in perspective, that's twice the mileage I used to get out of stiletto heel tips, and I don't think the quality of the product has changed significantly in the last 10 years. My non-stiletto heel caps have experienced the same relative increase in service life.
I like the self checkout at the grocery store (because I can bag my groceries my way in my own cloth bags), but I hate self checkout anyplace else. Actually, if they'd do like they do in most of Minnesota, and have a regular checkout but self-bag, I'd prefer that.
On edit: It occurred to me that in small file size, it may not be obvious that my mules, though predominately black, are rainbow colored.
