to increase friction
Oxygen creates a fire hazard (oxygen does not burn in itself, but it makes other things burn). In an environment where there is excess oxygen, you have to avoid sparks, including those caused by static electricity. And rubber soles on shoes, rubbing against a carpet, are a major source of static electricity. So with the right kind of shoe covering, you can avoid that problem.

The grooves on the soles of shoes and boots are known as the treads. Running shoes may have spikes for grip on grass running tracks. Football boots have studs, also for grip on an often slippery, grass football pitch.
Point shoes (ballet) and tap shoes are examples of smooth-soled shoes.
Runnign shoes have flexible rubber soles to absorb impact.
Girls' shoes do sometimes have soles. But if they don't it is often because grown ups think it is more comfortable for the girls to be without soles on their shoes.
golf shoes have rubber soles because it is a game played on the grass which needs to have stops at every step as rubber will increase the interlocking of friction, golf shoes have rubber soles
Wash your shoes.
Yes they do due to how much you walk on them. When your soles start wearing out it's time to get new shoes!!!!!!
soles of shoes are provided with design to increase friction
You need good soles so that they don't wear out too soon, or so that you don't slip. "Good soles" is relative; you need good soles on hiking boots, but not so much on dress shoes.
Yes there are. Tap shoes without soles make the shoe more flexible so you can stand on your toes.
