False
When a person walks on rough surface, he does not slide with respect to surface on which he is moving. Nature of friction is static. This static friction is responsible for his motion. In fact the direction of friction force on both the feet is opposite to each other. If the person accelerate, the forward direction `f_(1) lt f_(2)`
If he move, with constant velocity, `f_(1) = f_(2)`
