The shoes have a significant disadvantage. If they get dirty on the upper part, they cannot be cleaned at all. And they get dirty for no reason. When walked on and scuffed, the fabric (mesh) collects dust from the atmosphere and appears as a dark line. I tried with a brush, nothing. With a special shoe cleaner, the same. It only got worse as the white color became darker. After wearing them for 1 month, they are literally for throwing away.
