That’s not a cankle that’s a fat woman with shoes that are to small.
I think in some ways cankles are CAUSED by the high heel shoes that are foisted upon women as “attractive” by the fashion industry. I know many farm girls who don’t wear dress shoes much at all in favor of work boots and some despite being a bit portly don’t have cankles.
I think the stress of unnatural high heels screws up the muscles and fat distribution. The only high heels I will wear are cowboy boots. Some of those high shoes are torture devices designed by the gay men who have been running the fashion industry for the last 100 years.
