Special Offer  Q:Is it true that wearing heels can cause ingrown
toenails? If so, how can I prevent them? A:Heels can cause your
feet to slip forward in shoes, jamming your toenails into the
corners of your flesh, says NYC podiatrist Lori S. Weisenfeld.
But if you trim the nails straight across, in line with the tips
of your toes, and round off sharp corners with a file, you’ll
avoid any pinching.
