How to say "shoe sole" in Arabic

Naʿl is letter-for-letter Hebrew נעל, and both started as the sandal: Biblical נעל is the sandal itself (a sandal seals a land deal in Ruth 4), and Classical Arabic naʿl is the sandal too — Moses is told to take off his naʿlayn in the Quran. Then the two words went to different places: Modern Hebrew broadened נעל to cover any shoe, while Arabic naʿl slid down to the bottom: today it's the sole you resole at the cobbler, or naʿl al-ḥiṣān, a horseshoe.
