Friction is important for all sports.
Without it it becomes really hard to accelerate or deaccelerate.
For example a 100m sprinter.
It would be great for him if there wasnt any air resistance (as long as he can breath).
But he needs friction on the floor to push himself forward.
however friction is less useful in hockey, skiing, and almost all types of boarding(Snowboarding, wakeboarding, kneeboarding, sandboarding).
Friction is not useful in activities like ice skating and skiing, where minimizing friction allows for smoother and faster movement. Similarly, in sports like sailing and swimming, reducing friction with the water is essential for efficiency.
Sandpaper is high in friction but is not considered useful in terms of being helpful in a general sense.
stopping cars Friction is useful to start a fire with sticks.
Oh, dude, low friction and not useful? That's like asking for a list of things that are as exciting as watching paint dry. How about a feather in a vacuum, a sloth on a treadmill, and a banana peel on a frictionless surface? You're welcome for those thrilling suggestions.
Friction is not useful in situations where smooth movement or sliding is required, such as in lubricated machinery or in sports like ice skating. Additionally, in situations where reducing wear and tear is important, such as in engine components, friction is detrimental.

Ice skating does not require any friction because the skater needs to glide on the ice and if there was any friction on ice the skater would have trouble to skate smoothly on the ice. That is why ice skating does not require any friction at all from my perspective.
Brakes are meant to have a lot of friction and it's useful.

Friction is sometimes not useful as when a player drives forward in a wet condition the ball slows down due to the friction so it is harder to control and difficult to get a shot away. Also a player can lose momentum during fast strides or slip in wet conditions. The ball will slow down because of the friction with the grass so it is easier for the goalkeeper to save it.
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
