I’ve had flat….and I mean FLAT….feet since I was born. Absolutely no arch, and pronation to the extent that I can only walk a few minutes without orthotic support before my lower legs begin to cramp and burn. For years, I went to podiatrists to have custom-molded orthotics made, with varying levels of satisfaction and always high levels of expense. I’m not kidding when I say that these orthotics are BETTER….in terms of their support and comfort and ability to be customized to fit my shoes….than any custom orthotics I’ve owned. Plus, they’re light and MUCH less expensive. These insoles allow me to get through my day without discomfort, and they’re in all my footwear.
