If there was no friction between the soles of your shoes and the sidewalk, you would be endlessly sliding down it until your momentum stopped you or you ran out of force.
The breaks on your car require friction to make the car stop. Friction between the souls of your shoes and the ground keeps you from sliding.

Sure. When I am running, I need to have good friction between my running shoes and the ground that I am running on, in order to be able to run quickly. A car needs a good level of friction between the tires and the road to drive at a high speed. Otherwise the wheels just spin but the car doesn't move (this can happen when you are stuck in the ice).
Shoes have a higher amount of friction compared to other surfaces. If shoes did not have high friction, then people would be slipping and falling everywhere. I am sure shoe companies do not want this. But some shoes that do have low friction would be a dance shoe or bowling shoes, these are often slideing alot so they have lower amount of friction.
yes it can also reduce friction especially when its slippery, cleats reduce the surface area that are in contact between the shoes and the ground surface?
Snow decreases the friction between your shoes and ground. That's why cars slide in the winter.
Yes
friction is that force that opposes motion. for e.g friction between the road and your shoes prevent you from falling when you walk on the road.
by increasing the roughness of the ground or increasing the sole of the shoes

Friction between your shoes and the floor when you slide down a slide. cuz YOLO.

True. Brakes use friction between the pads and rotors or shoes and drums to stop vehicles.
