Why is it difficult to walk with new leather soles on a polished floor?

Question

is it because of a greater coefficient of kinetic friction?

Answer 1

Yes. Since the new leather soles are polished as well as the floor, the coefficient of kinetic fricction are very small and you tend to slip. Once you use the shoes in a more rough surface the soles gets rough increasing with this the coefficient of kinetic friction. I hope this helps.
