With warm weather upon us, flip-flops are a summer essential. But is it safe to wear them for long walks?
We spoke with Monique van der Kaa, a podiatrist and owner of Podotherapie van der Kaa. Specializing in athletes and chronic foot conditions, she also trains podiatrists on crafting custom orthotics.

Monique van der Kaa: "Around 30% of Dutch people deal with foot issues, often from ill-fitting shoes. Summer brings more flip-flop wearers to our clinic with forefoot pain, heel problems, ankle sprains, corns, and calluses. A pressure sensation in the forefoot signals overload, while stitches may indicate nerve compression—all linked to extended flip-flop use."
"Flip-flops suit casual spots like the beach, shower, or home, but skip them for lengthy outings. Poor grip forces your toes to 'claw' and hold on, straining muscles. A 30-minute stroll can activate foot muscles beneficially, but longer wear invites calluses, painful fissures, and trips. Birkenstocks provide better footbeds than basic flip-flops, yet they're no hiking gear. Choose adjustable sandals with Velcro for optimal fit and less toe gripping."
"To walk comfortably in open footwear without issues, opt for custom-made sandals from a podiatrist, pedorthist, or orthopedic specialist. A supportive footbed, secure strap, and precise fit deliver cushioning, stability, and zero pressure points—sliding minimized. Not everyone develops problems, even daily wearers, but risks build over time. Prevention is key."
