If the chappal is a bit tight, do not worry. It will grow on the foot as they are made from pure leather. It has the tendency to expand upon regular usage.
Do not keep the Chappal in a closed space for a long time.
Due to moisture, a white fungus develops on to the leather, there is nothing to worry, just brush it off.
Polish the Chappal once a week to enhance the look and shine.
Best to use in winter and summer seasons. (Do not use in water or rainy season).
