I come in pairs but you never use both at the same time on the same foot. I protect you from the ground but the ground is all I touch. What am I?

Question

Accepted Answer

Shoes. Shoes come in pairs — one for each foot. You wear one on each foot simultaneously, but neither shoe ever touches the same foot as the other. They protect your feet yet make constant contact with the floor.
