I occasionally use Easy Slide. I tap it lightly on my sole and then rub it in so that there is no loose residue. I do all this away from the bowling area. It usually lasts me for a few months without having to re-apply.
I have Dexters with interchangeable soles and heels, but I find that it's not the solution that many think it can be (not for Dexter's, at least). I can only use the #8 soles - the #6 and lower instantly stop for me, whereas the #10's are like ice skating. So, I use two different #8's - one with no Easy Slide, one with the little bit rubbed in. I have the same problem with their heels, too. Anyway, my point is that having interchangeable soles and heels sounds great, but it isn't always the answer.
