I've easily gone through 2/3 pairs a season for the last few years exactly for this reason, Just has to be done!!
Oh yeah. its an absolute must!!
And a good slide and pick up makes you look awesome in the field. everyone knows it. If you can do that you are class. You can see the batters discussing it after each over. 'Damn that guy slides, we wont be able to sneak 2/3 from him, we will have to try and score somewhere else'
Same if someone has the old canon arm with ZERO accuracy going on. 'Damn, he has a big arm, we had better stop running when he picks the ball up. And look how dirty his trousers are, he DEFINITELY slides a lot'
I should know, I've made my career from utilising those
'skills'
