They worked & they didn’t work.  The first time I wore them, I had the “nubby” side away from my arch.  They do make my feet sweat, which they never have before.  The next time, I found that I had not used them correctly.  The “nubby” side should have been against my foot.  Well, that was too painful. I will continue wearing them with the “nubby” surface away from my feet & just get used to sweating.
