Grip is a type of friction that people need in order to walk comfortably. Without grip, people would slide and have nasty falls.
as while walking we are in motion so the kinetic energy between road and foot will b kinetic friction....
Well it is either static friction or rolling friction
Rolling Friction
Walking is static friction because you do not drag your feet along the ground.
Gravity pushing you down on the earth and friction from the ground are the two types of friction you have to overcome when walking.
Friction can be a friend when walking and when driving a car. For example, walking or driving on ice can be very risky due to the lack of friction. Friction can be a foe when it causes more work to have to be done or excess heating. Friction is responsible for our getting blisters on our hands or feet.

Friction
You need to know both material involved in the friction to find the coefficient
Walking to move forward, same for anything that moves. If there was no friction it would be like walking on oil.

Friction:)
walking on the floor
Because your feet are pushing backwards and therefore the friction opposes in the opposite direction which happens to be the direction in which you are walking.
