In summer, the sunlight is strong and the ground temperature is high. Wearing sandals can prevent direct contact between feet and the ground, reducing the risk of foot injuries caused by high temperatures or sharp objects.

In terms of functionality, sandals are particularly suitable for wearing in summer because they can help keep the feet cool and reduce sweat secretion. High heels, on the other hand, are more commonly used to modify foot shape, widen leg lines, and thus enhance a woman's elegant temperament. High heels can also make the wearer look taller, helping to adjust body proportions.
