Adrianne Haslet-Davis recalled the horror of losing her foot during the 2013 Boston Marathon.
"All of a sudden we heard a loud blast and the first bomb had gone off and we knew, just by the sheer sound of it and the smoke that it wasn't something that was just a, you know, fun explosion of confetti or anything like that," Haslet-Davis said. "I just kept screaming out, 'I'm a ballroom dancer, I'm a ballroom dancer, please save my foot.' And I just kept screaming it over and over again."
The story is similar to that of Amy Palmiero-Winters, who lost her leg during a motorcycle accident in 1994.
"Doctors had said that 'you'll never walk again,' and it was my spirit and determination that told them, 'Yes I would,'" she said.
Determined to help others walk, almost two decades later, Palmiero-Winters is the director of A Step Ahead Prosthetics in Hicksville, Long Island. She said the struggle of the marathon victims is not lost on her.
"You wake up one day and you've lost a part of your body. How are you going to walk? How are you going to function?" she said. "For children, how are you going to get back to school and play with your friends?"
That's why A Step Ahead is donating prosthetics to the children who lost their limbs on that fateful day in Boston.
But Palmiero-Winters said that at this point the focus is on getting the victims healed.
"The doctors and the surgeons are all doing their jobs to get them to the point where they can start the process of walking again and wearing a prosthetic."
A step ahead has contacted the hospitals in Boston and will be sending a team out there to work on prosthetics for the children.
A Step Ahead Prosthetics in Hicksville, Long Island, customizes prosthetics for people from all over the world. There are cosmetic ones made to mimic actual skin and lightweight "blades" made of carbon graphite designed for running. Aviva Drescher of "The Real Housewives of New York City" wears a prosthetic.
