Just adding, as AJ mentions, many of us older people on YLF have learned the hard way that wearing heels too often can trash your feet, posture, spine, etc.
In my 20s it was the time of power suits and women wore heels, hose and skirt suits with shoulder-padded jackets. That was the daily, expected work uniform. There were many women that would wear sneakers to commute to work, then switch to heels once they arrived. There were many men and women who thought that this commuting look - while highly practical and quite smart - looked tacky. I was one of them. And now I regret it.
Flash forward 20 years later, and those days of daily high-heel wear (pointy-toed heels) really did a number on me. I have suffered back problems on and off for years, and I have dealt with bunions on my foot from squishing into pointy-toe heels. I.e., daily wear of such shoes leads to physical deformity of your feet, and shortens your calf muscles, which leads to lower back issues.
I have been in and out of PT to address these issues, and it's been mentally, emotionally hard for me over the years to face up to the idea I have to sacrifice a certain level of fashion for my health. I had no problem switching to 1 to 1-1/2 inch heels - but giving them up entirely, and resigning myself to only orthopedic-type shoes... no! Call me vain or whatever, I just had a really hard time with that!
My DH made it much easier for me about 5 years ago: he suggested that every time I buy a pair of heels, I *also* buy a cute pair of flats!!!
This was a great strategy, and now I own an equal number of flats to heels. I have learned through the last 5 years that I can still wear the heels, I just have to be very judicious about when, and for how long, and alternate.
I have found that rotating shoes - no matter whether they are "comfort" or orthopedic brands or fashionable back-killing brands - is very important to overall health.
What's been working for me is to reserve the heels for those occasions I'm not walking all that much. Get a big purse and keep the heels in them, and wear fashionable but comfortable and practical flats to walk to wherever you're going. Then switch into the heels for a few hours. The next day, wear flats all day to even things out.
I would say I wear flats 80% of the time, and heels 20% of the time. And interestingly, I've learned that for flats I need to size up 1/2 size, to accomodate foot spread as the day wears on.
Also, I need to keep up with yoga - when I am consistent with the yoga, my bunions actually reduce in size. I know i'm wearing heels too much if my bunions start to enlarge and bother me.
I would like to be able to wear heels - On occasion - well into my later years. My mother is 68 and cannot wear heels at all anymore. She can only wear a certain orthopedic style shoe, her feet are that fussy.
Lesson for the younger YLF'ers: baby your feet now, if you want a long life of fashionable footwear in your future!
