Worse than nothing at all
I tried using this product for several weeks. During that time, my plantar fasciitis never improved. That in and of itself wouldn't warrant giving a one-star rating. What earns that, is that the top of my foot became numb through the use of this product. Ended up throwing this thing away as it was literally causing more problems than it solved. Stay away from this product and save yourself some money, frustration, and pain.
