Improper sandal use threatens foot health, experts warn

High summer temperatures increase foot sweating, creating conditions for fungal infections, especially in shared spaces such as pools, gyms and changing rooms. Podolog Fahrettin Başar of Okan University Hospital stresses that tight or overly loose sandals can cause heel cracks, blisters, and promote moisture buildup, while prolonged use of thin flip‑flops may lead to plantar fasciitis, Achilles tendon problems and altered gait that affect knees, hips and lower back.

Physiotherapist Ahmet Burak Sezgin adds that inadequate support from sandals can trigger a cascade of musculoskeletal issues, including Morton’s neuroma, metatarsalgia and even neck or jaw strain. Both specialists recommend shoes that fit snugly without compression, provide arch and heel support, allow ventilation, and are made of moisture‑wicking materials. Daily foot hygiene—washing with warm water and soap, drying between toes, wearing clean cotton socks, and avoiding shared foot care tools—further reduces infection risk. Diabetic patients are urged to inspect their feet each day and seek medical attention for any wounds or color changes.
