What does the "detachable accessories" promoted by 7or9 high-heeled shoes mean?

I searched their news. Simply put, 7or9' s high-heeled shoes are minimalist pointed stilettos, and the shoes themselves don't have any accessories. All accessories, whether it is the decoration of the toe, the buckle of the shoe body or the pendant at the heel of the shoe, are matched by the user himself. When you don't need accessories, you can remove them and keep them simple and generous.

The following information is for reference:

At present, almost all high-heeled shoes accessories on the market are integrally formed with shoes or fixed in a certain position. In contrast, 7or9 has designed and developed a series of accessories such as side clips, buckles, ribbons and pendants, which can be used for toe, sole and heel respectively. They are elegant, playful, retro or handsome, with diverse styles, exquisite and interesting.

above, for reference, thank you.
