I have one of those fake grass Astroturf mats and it
works very well for scraping crap of the shoes

But it "catches" dirt as well since the design of the
mat doesn't allow stiff to "fall through".....
especially if I get snow or ice

Anyone have advice on a mat that has some big "holes"
in to allow one to pick it up and shake the snow, ice,
dirt out of it?
