Rough, tough.
This is very firm plastic, and is too hard to be enjoyable, almost painful. I was expecting a softer jelly-type product, or something similar to silicone....nope!  I do not have any foot health problems, but know people who do, so want to warn that if you have neuropathy or diabetic issues, stay away from this.  The packaging was good, ship speed good.
