Friction is useful in many countless ways:
1. Friction helps us to walk. It doesn't lets you go sprawling each time you walk. Same is with running. 
2. Every mechanical machine you have ever seen, any mechanical tool, hammers; nails; pliers, all work due to friction. Gears and conveyor belts won't work if there was no friction. 
3. Friction also helps you feel. Take it this way: when you feel a surface, it is because there are very small grooves on it which give the surface roughness. Now, when there is 0% friction, I don't suppose you will ever be able to feel a surface again.

The disadvantages of friction are:
Heating effect: This heat may be useful when you got cold hands in winters and you rub them together to get some warmth but this heat is also the reason your appliances like food processors, lighters etc. go dead. Same is with car tires. 

Hope this helped you!
