when you walk you push the ground backward . your force is given on a large mass so the ground acceleration is negligible . now according newton third law of motion there is a reaction force which acts on less mass so you accelerate in other way you move . no if there was no friction and when you push the ground backward you would slip . friction force gives you the grip to move forward

There is some opposing force that acts on our shoes or legs when we walk on a surface. It is popularly known as friction. When you walk on a plane and smooth surface, the friction is less and we slip. It is because there is no opposing force which gives us grip. That opposing force helps us from not falling and it is not so powerful that we can't take our legs off the ground. This way friction helps us in walking.
