How can one perform Tawaf and Sa'i during Hajj when suffering from flat feet that necessitate the use of orthopedic insoles inside shoes or socks?

It is forbidden for a person in a state of ihram (definition) for Hajj or 'Umrah (definition) to wear khuffayn (leather socks or boots) or anything that covers the ankles, such as regular socks or sports shoes. It is permissible to wear boots and sandals if they are below the ankles. The basis for this is the prohibition by the Prophet (peace be upon him) against wearing khuffayn, except for someone who cannot find sandals, provided that they are cut below the ankles. Ibn Taymiyyah held the view that a cut khuff is not considered a khuff, and it is permissible to wear it in all circumstances because it resembles permissible sandals and does not fall under the prohibition. If a person in ihram needs to wear something that covers the ankles due to a necessity (such as wearing orthopedic splints), it is permissible for them to do so, but they must pay a fidyah (definition). The fidyah is feeding six needy persons, or fasting three days, or sacrificing a sheep. There is no sin upon them if the act was due to a necessity; however, if it was without necessity, they are sinful and must pay a fidyah. It is permissible to walk with clean shoes in the Mas'a (Sa'i area) and the Mataf (Tawaf (definition) area).
