Nicer than I expected.
So far, I've walked between 10 - 20 miles on these, and they show barely any wear.  The only difficulty is that, with rubber-heeled shoes with a heel that I could not nail into, it took a little experimentation to find a glue that would stick these on successfully.<br /><br />First clean the shoe bottoms with alcohol, let them dry thoroughly, then use Loctite 1906107 Super Glue Ultra Gel glue.  It takes a few minutes to set, and you should give them at least 12 hours before you walk on them, but it works great if you follow these precautions.
