At my SSPX chapel it seems to have become a contest among all the young girls, and even the young mothers under like 45, to see who wears the most immodest worldly footwear. Here are some pictures, below. They look like they are "easy", loose women of the world, to say the least. I think that the same women would wear cow patties on their heads if the fashion industry pushed the idea. Airheads.
Not only are those multiple spiked shoes on the top left a temptation for men because they change the way a woman walks and make her look seductive, but also because they look like they could inflict a lot of painful injuries. They could be used as weapons knowingly or unknowingly.
The shoes on the bottom right are likewise dangerous, not only for the woman wearing them, but also for others around her.
When I lived in San Francisco, ladies would wear sharp "spiked" high heels to the wharf when dining at restaurants. These spike high heels would often get caught in the cracks on the wharf. When that happened, the gal could fall and injure herself or injure others around her during her fall. Often the heel would break off, then she would have to remove her shoes and walk barefoot . This was dangerous because she could get wood splinters in her feet or step on sharp nails.
These shoes are not comfortable, practical, or good for one's foot and leg health. When I was young, and girls wore these shoes to a dance, they would kick those shoes off and go on the dance floor barefooted. Some girls would carry ballet-type shoes in their bags and quickly change into them.
