I am aware of three, that can be relevant in some cases. 1) Energy losses, 2) increases wear and tear, 3) produces heat.
- ice skating
- produces heat
- energy losses
friction is useful for: you to walk It is needed for braking Can be used to produce heat
It allows you to walk (with out friction between you and the floor this wouldn't be possible) It is needed for braking can be used to produce heat
stopping cars Friction is useful to start a fire with sticks.
yes friction is very useful because it help objects not to slide or slip
High friction is useful for lots of things, like a goalkeeper's glove. The more friction there is between the glove and the ball, the easier it is to get a hold of it.

Friction can be useful for stopping cars when the brakes are put on, if you're running and need to stop quick, so basically to get grip. Also friction is good for fires and warmth.

fricton is useful in many many ways: help in protecting from slipping protect the car from sliding due to friction you can make fire from rubbing two stones. etc......... etc....
Enables cars to move, rather than just spin tyres and go nowhere.
Friction is very useful but it has its own disadvantages. Friction causes wear and tear. Friction spoils the soles of our shoes. friction reduces speed This is all wrong some not useful types of friction are are when airplanes fly the friction causes heat that materials that will withstand which are costly.
Brakes are meant to have a lot of friction and it's useful.

No Friction Runes Computers
the friction from pushing the hull through the water is not useful as long as you're travelling.
It can be useful when a ball is catching
