Washing The Ankles (or Any Other Part) During Wudu
This is fiqh where opinion of Jurists has been mentioned. We should not indulge in too many doubts, especially when directives relate to acts we do normally in daily life. If its washing of feet to the ankle, we should just stick with the primary directive of washing feet to the ankle, in ways we usually wash them i.e. through pouring water, through spreading water etc. all of these fall within ambit of washing feet.
