Don't waster your money.
They're very thin, imagine a cheap clear car floor mat pretty much the same thing but it has magnets. It's a sock color magnet, after a day or so it takes on wathever color sock you're wearing. They kept sliding to one side of the shoe so I had to constantly keep adjusting it. During that whole process the magnets kept falling off and after a few days my left foot started to ache, I finally gave up and threw them in the garbage where they belong.
