These boots were made for slipping.

Demi Moore strapped on boots with a high heel when she ventured out at the Sundance Film Festival in Park City, Utah, yesterday and nearly took a tumble.

People who were with her were able to catch her before she fell onto the snow-covered sidewalk.

Moore, 48, is there promoting two movies, “Margin Call” and “Another Happy Day.”

Earlier in the week, “Another Happy Day” co-star Ellen Barkin disclosed that Moore has strong thigh muscles, London’s Daily Mail reported.

In a scene in the movie, Moore wraps her legs around Thomas Hayden Church “and he sadi her legs crushed his ribs,” Barkin said.
