Is it permissible for a person to buy sandals for three thousand Saudi Riyals (SR 3000)?

Excessive spending beyond moderation and common practice is blameworthy extravagance. This varies according to people's circumstances. If purchasing shoes at this price does not deplete a person's wealth and is not considered blameworthy in their environment, then there is no harm in it. However, it is preferable to be thrifty and direct one's money towards what benefits them in their religion.
