I recently took a job in a shoe repair store. Although I myself have not worn high heels in over 20 years I now make part of my living from fixing them. It has been an education.
There really are some heels better constructed than others.
Not a week goes by I don’t have to tell some woman that her high heels are beyond repair, quite often due to absolute crap construction - flimsy materials, off-center or asymmetrical shoes, and so forth. However, some women do it to themselves. Ladies, buy shoes that fit! Yes, yes, I know that’s a cute shoe but buying a cute shoe then coming to me to ask if I can stretch it so it fits you is, um, how shall put this? Not using your brain. And I’m sorry, dear, but your foot is NOT a size five. It’s at least an eight, like mine. I know they make heels our size because I see them almost every day, so try to purchase something that fits. And if you’re 300 pounds your shoes just aren’t going to last as long as they do for the 120 pound woman you’re standing next to. However, if you buy shoes that fit they really do last longer - we’ve got at least two guys bringing their own heels in (yes, gents who dress up as women, though they come to the shop as men) and if a six foot tall two hundred pound man with a size 12 (men’s) foot can find a heel that fits so can you, sweetie. Yes, he paid a lot of money for that three inch heel, but maybe that’s why he babies them. They’re old, but they’re in great shape.
That, and when the heels tips start to go, get them fixed. BEFORE it starts to eat into the base. Yes, I know, sidewalk gratings and other hazards can cause significant damage in one step, but there’s a reason office workers have been wearing "practical’ shoes and flats on their commute and changing into heels once their in the office for at least the past 30 years. I see women come tottering in to the shop with one heel ground down lower than the other, half the time complaining their feet/legs/back hurt, and oh, could I please fix this pair of shoes. The two problems are related, honey. It’s also cheaper to fix 'em when it’s just the rubber tip and you haven’t worn down any other structures.
That, and if you buy cute-but-cheap shoes accept that many of them simply can’t be fixed. Enjoy them for the short time you have them, but realize that they just aren’t going to last forever.
