Medical experts continue to issue warnings regarding improper footwear and its role in long-term foot damage. Orthopedic surgeons and podiatrists have noted that thin or flat footwear, such as indoor slippers or flip-flops, increases risks for heel pain, muscle overload, and plantar fasciitis due to a lack of cushioning and stability. To mitigate these risks, experts recommend structured sandals with shock-absorbing soles and arch support.

During heatwaves, health professionals are focusing on managing heat-induced edema—the swelling of feet and ankles caused by heat dilating blood vessels and slowing venous return. To combat this, nutritionists and specialists suggest regular movement, such as walking for at least twenty minutes a day, to activate the calf muscle pump and assist blood flow. Sports traumatologist Juanjo López has added that high temperatures, humidity, and prolonged standing can exacerbate swelling, heaviness, and chafing. He advises wearing footwear with a wider toe box to accommodate natural foot expansion and using breathable materials.

Expanding on these concerns, Dr. Frédéric Saldmann emphasizes that the body relies on the feet as a foundation, noting that improper support can negatively impact walking and equilibrium. Podiatrist Maud Falconnet specifically warns that summer footwear choices can exacerbate conditions like hallux valgus (bunions). She identifies pointed toes, high heels, and sandals lacking solid support as the three worst types of summer shoes, as they increase friction and pressure when feet swell in the heat. Experts suggest observing uneven sole wear as a potential indicator of postural issues.
