Flip-flops are one of the most popular types of sandals because they are cheap and versatile, especially for a day at the pool or the beach. However, experts want you to be cautious when wearing them. According to the American Podiatric Medical Association, flip-flops aren't good for walking long distances or playing sports because they have little shock absorption and arch support which can lead to injury.
On this note, people with diabetes should be especially cautious of the shoes they wear. Diabetes can cause peripheral artery disease which reduces blood flow to the legs and feet and the ability to feel pain in those areas. Therefore, a diabetic person is at risk of having a foot injury and not noticing it until it's too late and amputation is required.
"(People with diabetes) really need the protective function of something that covers their toes. I'd much rather see them in Crocs or something that has a covering on top," said Jim Christina, director of scientific affairs for the American Podiatric Medical Association (via WebMD).
