Yes. High-heel pain. Beauty comes at a price. Let's be honest. A plastic surgeon in l.A. Says he has found a way to end high-heel pain. It's a spray, designed to numb your feet for hours. Abc's cecilia vega strapped on her stilettos to give it a try. Reporter: The agony of high heels. Could this be the cure? Magic in a bottle? Meet the newest product. It's called heel no pain. A numbing spray that hits store shelves in two weeks. And it claims to make possible what so many women thought, inconceivable. Comfortable stilettos. It diminishes the pain completely. It puts it on the back burner. Reporter: The man behind it, beverly hills plastic surgeon, dr. Randall hayworth. We have the same medication, lidocaine, that dentists use. Reporter: You spray it on your feet. Wait 10 to 15 minutes for it to kick in. And go back to dancing, strutting, not complaining at your barking dogs. But -- there's a but. Critics say there are risks. That pain in your feet is there for a reason. Something's wrong. It's not really curing any problem. It's really just masking pain. So, it's important to be able to listen to your body and receive any signals that it's sending to you. Reporter: And too much time in the stilettos, doctors say, can be dangerous. Arthritis. And even foot deformities, bunions, hammer toes. Reporter: I'm going to spray one foot and see what happens. I wait and wait and wait. And the results -- okay. The foot without the spray, it feels like a foot that's been in a high heel all day long. It kind of hurts. The foot with the spray, it kind of hurts, too. I don't really notice that much of a difference. Dr. Hayworth says it works on 70% of patients. Maybe I'm just one of the unlucky ones. I'm sticking with flats. For "good morning america," cecilia vega, abc news, los angeles. I like cecilia's idea. I have a pair of flip-flops or boots ready to go. These heels that we have on right here, two hours. Two hours, max. And I'm done. I dunk my feet in a bucket of ice water. Do you really? I'm totally kidding. Oh. That's my way of numbing things. I do that before every show. That was so easy. I know. You men. Lara, you have christmas
