Summer sandals may keep feet cool but certain styles can increase the risk of pain and injury, according to foot health specialists. Podiatrists say footwear with minimal support, thin soles or insecure straps alters gait and places extra strain on the plantar fascia, forefoot and Achilles tendon, leading to conditions such as plantar fasciitis, metatarsalgia and tendon irritation.
Shoes that offer insufficient cushioning or arch support force muscles and ligaments to compensate, while very flat flip‑flops and loose slides can permit excessive foot motion and rubbing that causes blisters and calluses. High platform or wedge sandals change ankle position and load distribution, which can exacerbate forefoot pressure and increase the risk of sprains during uneven walking surfaces.
To reduce problems, specialists recommend choosing sandals with a contoured footbed, firm sole and a defined heel cup to stabilise the rearfoot. Adjustable straps that hold the foot securely and a slightly raised heel (rather than completely flat soles) help distribute pressure more evenly. The American Podiatric Medical Association provides guidance on footwear and awards a Seal of Acceptance to models that meet basic foot‑health criteria; consumers can look for supportive features rather than style alone.
Practical measures include limiting long walks in flimsy footwear, rotating footwear types, and using over‑the‑counter cushioned insoles or custom orthotics when recommended by a clinician. If pain persists—especially persistent heel pain, numbness, swelling or difficulty walking—seek assessment from a qualified podiatrist or medical professional to receive a diagnosis and targeted treatment, such as stretching programmes, physical therapy or orthotic intervention.
