3 ways of decreasing friction in shoes is to put in shoe cookies (shoe pads), bandaids, or stuff them with toilet paper.
by increasing smothness wecan decrease the friction and vice versa
when i am ask is friction important i say the answer is yes. friction is important and can help people in many different ways. like cars for a example cars use friction to drive on the road. there is many different types of friction to; dry friction, fluid friction, lubricated friction, skin friction, internal friction, ect..... all of these types of frictions can be different a different way.

Important factors in decreasing Kinetic Energy are Gravity and 'drag' from Friction.

You can minimise friction by Decreasing surface area, making area smoother, lubricating it(eg. car parts) and the opposite to maximise friction.
Decreasing the mass or Decreasing the velocity
