All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad , is His slave and Messenger.
It is forbidden for a woman to wear an ankle bracelet outside of her house if it jingles and produces sound which non-Mahram men (those who are Islamically lawful for her to marry) can hear. Allaah Says (what means): {And let them not stamp their feet so as to reveal what they hide of their adornment. And repent to Allaah all of you, O believers, that you may be successful} [Quran 24:31].
The feet of a woman are part of her 'Awrah (parts of the body that Islam mandates to be covered). They should be covered from the sight of all non-Mahram men, according to the consensus of all the Muslim Scholars .
On the other hand, a woman is permitted to wear any kind of golden ornament. She can wear a wrist bracelet, an ankle bracelet or any other ornament. She can go out wearing them provided no alien man sees them and that they do not produce sounds.
Allaah Knows best.
