Is it permissible for a woman to wear an anklet on one foot, and does this fall under the prohibition of wearing a sandal on only one foot, and can this be analogized to the prohibition of wearing an earring or a bracelet on only one side?

The Prophet, peace and blessings be upon him, forbade walking with one sandal. The reason given for this is that it deviates from fairness to the limbs or causes an imbalance in walking. As for wearing an anklet on one foot, it is permissible for women because it is part of their customary adornment, and the ruling for a single sandal does not apply to it. A condition for the permissibility of wearing an anklet on one foot is that a woman must not display it in front of non-mahram (definition) men, just as she must generally conceal her adornment.
