Is it a condition stipulated by the Hanbalis for the permissibility of wiping over the khuffs or socks that they do not give volume or define the shape of the feet?

The Hanbalis did not stipulate for wiping over leather socks (khuffayn) or regular socks (jawrabayn) that they should not show the shape of the feet. Rather, they stipulated that they should not describe the color of the foot due to their transparency, because anything that describes the color is not considered a covering. They also stipulated that they should not be wide such that the obligatory wiping area is visible through them. The leather sock (khuff), by its very nature, describes the foot.
