Friction is useful in helping to prevent objects from slipping or sliding when a force is applied to them. This is why we are able to walk, drive vehicles, and grip objects with our hands.
You can reduce friction by using lubrication, like grease for bearing, sewing machine oil etc.
use lubricants it smoothens the surface and reduces the irregularity between both the surfaces resulting in reduction of friction
One way to reduce friction is to use lubricants such as oil or grease between the surfaces that are rubbing against each other. Another way is to use smoother surfaces or materials that are designed to have lower friction coefficients. Additionally, keeping surfaces clean and free of debris can help reduce friction.

Use spiked soles or oversoles. This is what climbers do.
Friction's just one way.

Cars don't get better gas or mileage.
One way would be to reduce the friction factor.
You can reduce it to a point it is not noticeable but can not eliminate it altogether. You can reduce friction through use of materials with lower coefficient of friction like PTFE or by changing the way the materials contact, say change a sliding one to a rotating one.
