I say, and with God's help: It is a small khuff (a type of footwear) worn over the khuff to protect it from mud and impurity. Its shaft is shorter than that of the khuff, but it covers the ankles. The various types of shoes worn today are considered to have the same ruling as the jirmuq (a type of footwear) if they meet certain conditions, which are briefly: The first condition: They must cover the ankles. The second condition: It must be possible to walk in them for a distance of a farsakh or more, which is approximately five kilometers, without difficulty and without wearing anything over them. The third condition: They must stay on the feet without being tightened, meaning they should be tailored to the size of the foot. The fourth condition: They must prevent water from reaching the body when wiped over them; due to their thickness, as thin materials allow water to pass through. The fifth condition: Each of them must be free of a hole that shows three fingers from the smallest toe of the foot according to the correct opinion, not less than that. However, if the hole is small enough to show less than three fingers from the smallest toe of the foot, it is permissible to wipe over it. Refer to: Al-'Inayah 1: 155, Sharh Al-Wiqayah p. 114, Nihayat Al-Mirad p. 386, and God knows best.
