RE: Physical designs from another planet.

The issue here isn't so much that the shoe doesn't slip, the point is that women shouldn't have this problem.
If I were a woman, I would wear a different type of shoe. I've seen many young women who avoid this type of shoe precisely because of this. In fact, since 2020, many women have been seen wearing low-heeled shoes and sneakers. But as I always say, it's a matter of taste, and everyone's opinion is respectable.
