What should you wear? Go for “a low heel [with some kind of back] with a wide sole,” says Dr. Emily Samuels, an assistant professor of geriatric medicine at the Icahn School of Medicine at Mount Sinai in New York. “There’s a higher surface-contact area with the ground and then a slip-resistant outsole.” Also, look for slippers that can tighten around your feet. “Some kind of secure fixation, like Velcro or laces, prevents the flopping around,” she says. —Abigail Seaberg
