While performing wudu', one can wipe over (the top of) their clean, indoor boots once with wet hands instead of washing the feet.

• Boots should be waterproof and cover the whole foot up to (and including) the ankles. They must have no holes wider than three fingers in width. It does not matter if their mouths are so wide that the feet can be seen when looking down at them.
• They must be fit, strong, and tough enough so that the feet would not come out of them, and they should not fall down when walked in for 3 miles.
• They cannot be made out of wood, glass, or metal.
• One must put on the boots after washing one's feet while performing ablution. One can wear it for a whole day if one is resident. If traveling, one can wear it for 3 consecutive days.
