Well it is either static friction or rolling friction
Grip is a type of friction that people need in order to walk comfortably. Without grip, people would slide and have nasty falls.
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
It is important during walking so you maintain balance over any type of surface.
Walking to move forward, same for anything that moves. If there was no friction it would be like walking on oil.
Walking , if there is no friction you wont be able to walk properly . Another important thing is driving . In the absence of friction the car wheels wont be able to rotate probably thus the car will just go in circles.

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.
It is due to friction of your feet with the ground only, that you are able to walk. It is due to force of friction only that your car stops. Other wise as per the Newton's law of motion, the mass in motion continues to be in motion and the mass, which is stable continues to be stable. Here in walking you use energy in your body. Friction is necessary to start walking, to continue the walking. Friction is only responsible for that you do not stay in motion.
