Hope it may helps you

Answer 2

It is tough to write on a smooth surface. This is because the smooth surface provides less reisitance or friction. So the writer has less control over his pen as the tip of the pen tends to slip on the smooth surface.
SO is also the case when someone walks on smooth surface, he tends to fall rather than walking on rough surface. So is the reason why the below portion of shoe is not made flattened.
