Yes thats true
most of my ablution time is taken by the Miswaak, and washing my feet. Umar RA has said "Save ur heels from hellfire" so i rub my feet and in between its toes real well, lol. Furthermore, ladies need not go for pedicure anymore, this rubbing da feet process softens the feet and keeps it clean, Imagine if u clean several times a day, no need for pedicures lol
