Summer Shoe Threat-o-Meter

Casual Sneakers

Danger ranking: 4! "I have a lot of patients who come to me with heel pain from plantar fasciitis or heel spurs that they developed from wearing very flat sneakers that don't offer support."

Best for: Cruising on a bicycle built for two; chilling at a backyard barbecue

Avoid: "They may look sporty, but they're not intended for walking or standing for long periods of time."

Doctor's note: "I work with a lot of professional women who think these are their 'safe shoes,' but they can cause a lot of problems."
