text: My podiatrist recommended I get these after suffering from 3 bouts of plantar fasciitis. My only complaint is that I don't feel as if they do much for my non existent arch, and they don't fit in many of the shoes that I usually wear because I can't replace the insoles. That's not the fault of the product, but I've only been able to test these with two shoes.<br /><br />I was able to go to the county fair this summer and stand around and walk in them for 6 hours, by which my feet were already hurting, but the next day there was no foot pain. I largely attribute that to the product.I did have to trim off a couple of inches to get it to fit my shoes, and I like that the heel cup is deep enough to help prevent your foot from slipping and rolling around inside the shoe.
