Danger ranking: 3. If you're choosing between a wedge style or a completely flat espadrille, pick the wedge. "It offers a little more support," says Brenner. "And the rope soles can provide more of a lift than thin ones. These are good for light activity—walking or standing in moderation—but not much more than that."

Best for: Family reunions; picnicking in the park

Avoid: Energetic frolicking (especially in the rain)

Doctor's note: "The fabric would be more comfortable for those with calluses and bunions that are irritated by leather straps and hardware," says Brenner.
