These really work!
I have been using these for several months (and through the hottest summer I can remember).  You can actually wear shoes with no socks and these are quite good at keeping odor and wetness away.<br /><br />I ordered from their website and put them in a pair of well-worn, slighty-stinky shoes.  You wipe out the inside of the shoe with a wet cloth to help the rubber backing stick.  After the first day, the old odor was gone from the shoes--I was delighted.  I put them in all my closed new shoes now, and they  keep the insides looking nice and new.<br /><br />i have not tried them in sandals or clogs (because the clogs have cloth footbeds that the rubber can't stick to).  I have also not tried them with socks or stockings--mainly because that would defeat the purpose of using them.  But I can say that they keep bare feet dry and odor free in closed shoes with non-porous insoles.<br /><br />After a while, they do sort of wad up while you are wearing them, but I have noticed that this is about the time they are ready to be changed, so that may just be that they are past effectiveness and my feet are getting sweatier.<br /><br />I am so happy to see them on Amazon Prime now!
