NEW YORK (CBSNewYork) — Spring is finally here, and that means many women are getting ready to ditch their boots for some strappy heels.

But while they may be pretty, those shoes can cost you — from foot issues to ankle injuries to even a bad fall.

Karena Wu from Active Care Psychical Therapy stopped by the CBS2 studios to offer some advice on choosing heels.

Wu said the biggest mistake women making is “picking fashion over function.”

She said stilettos are among the worst shoes.

“Because of the pinpoint tip of the stiletto, this is a really narrow base of support under a pretty wide heel,” Wu told CBS2’s Diane Macedo and Andrea Grymes. “You’ve got to have good leg conditioning, ankle balance and calf strength to walk around in this.”

Wedges, meanwhile, get the thumbs-up from Wu.

“Wedges are fantastic because there’s support along the entire length of your foot,” she said.
