Ok, I got my new Platinum 24 put away in my garage Friday. Sweet looking machine! Most of what I blow is on cement. Some of it is a little irregular in my driveway. I set my shoes to about 1/8 inch below the blade. I got to thinking about reading somewhere about changing out the shoes for a heavy duty type of shoe but I really don't know what benefit that would be. Does Ariens sell such a thing and are they really any benefit?
