Is this a gimmick or really useful? I don't know.
After I bought this item in some enthusiasm to do all I could about my plantar faciitis symptoms, I heard from my foot specialist that he doesn't particularly recommend such a product. I am already stretching alot with yoga, so I don't think I'm in quite as much need for it as someone else. But I do use it occasionaly.
