There is a good amount of less noise when this is folded down I believe. I have a bzillion pairs of FitFlops. Fit great It turns red while charging but when there is no controller in the charger the green light is on. The mechanical action is smooth. But other than that its precious. Toe nail fungus means six months of prescriptions. 5 and it is usually hard to find shoes that perfectly fit. Now looking for another pair, different colour. I definitely recommend buying these because they?re a perfect dupe!
