What is the ruling on selling women's high-heeled shoes, knowing that this is the sole livelihood of the seller, who is trying to avoid selling them?

Selling and wearing high-heeled shoes is, in principle, permissible, unless it is proven to cause harm to the wearer, in which case it is prohibited due to the harm. Or, if the sound they produce attracts men's attention, then it would oscillate between being disliked (makrooh) and prohibited (haraam). Likewise, if such shoes are characteristic of disbelieving women, then it is prohibited due to imitation of them. In summary, the original ruling for these shoes is permissibility in selling, wearing, and buying, and it does not transition to prohibition or dislike unless there is established evidence.
