Thanks to the popularity of sky-high heels, many women will often stow roll-up flats in their purses for foot pain emergencies. However, podiatrists like Kendrick Whitney at Temple say they're just as bad as flip-flops and UGG boots, which have long been on foot doctors' worst-footwear lists. He advises women to not let their foot pain get that far: "There are things [podiatrists] can recommend to help women select shoes right for their particular feet that reduce stress, provide comfort, don't change weight patterns and still are fashionable," he said.
