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.
In sports like skiing or Snowboarding friction slows you down. That is why you wax your board or skis.
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.

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.
"Some of the companies that provide winter sports insurace are TravelInsurance, Insureandgo, Wintersportsinsurance, and Gosimply. These companies provide protection if you are injured from skiing, snowboarding, or other winter sports."
Friction can be very useful in your life. You need low friction when you ski. If you have high friction you cannot glide easily on the snow. You can also use low friction when you ice skate. If you have high friction you cant glide across the ice. When you use your laptop your keypad has to be able to glide. Some examples of high friction are erasing with your pencil, rubbing your hands together etc.
Friction converts mechanical energy into heat, which is rarely useful, and which can never be recovered in its entirety. Due to conservation of energy, this heat energy is not available for other things, i.e., for useful work.
The type of friction that benefits in some or other way like smooth running of vehicles on the road is called Useful Friction whereas other wherein it becomes a causative factor for wear and tear or damage to the object in question.
