Medical experts in France are warning the public that wearing flip-flops all day during the summer can cause significant foot injuries [1].
This guidance comes as a response to common summer footwear choices that lack structural support. Because flip-flops provide minimal stability, prolonged use on hard surfaces can lead to chronic pain or acute injuries.
Dr. Jean-Marc Sène said that flip-flops are not adapted for prolonged walking in city environments [1]. The lack of arch support and heel security increases the risk of instability when navigating urban terrain.
Specific injuries associated with these sandals include blisters and sprains. Dr. Gérald Kierzek said that wearing flip-flops throughout the day increases the risk of these conditions [2]. To mitigate these risks, Dr. Kierzek provided six safety tips for those who choose to wear them [2].
However, not all experts agree that the footwear can be worn safely. Dr. Daniel Benjamin said he advises against wearing these flip-flops this summer [3]. This contradiction highlights a divide among specialists regarding whether the risks can be managed through cautious use or if the footwear is fundamentally unsuitable for daily wear.
Common issues cited by the doctors include joint pain and general foot fatigue. When the foot is not properly supported, the muscles and tendons must work harder to maintain balance—especially on concrete or asphalt.
Podiatrists suggest that while flip-flops may be appropriate for the beach or short durations, they should not replace supportive shoes for daily activities [1], [2].
“"Porter des tongs toute la journée augmente le risque d'ampoules et d'entorses."”
The warnings from French podiatrists emphasize the tension between summer fashion and orthopedic health. While flip-flops are culturally ubiquitous in warm weather, the lack of anatomical support can lead to long-term joint misalignment or immediate injury. The differing advice between providing safety tips and recommending total avoidance suggests that the risk level depends heavily on the individual's foot health and the surfaces they traverse.
