Why would it be more comfortable to walk on hot beach sand with flipflops than without them?

Walking on hot beach sand with flip-flops is more comfortable than walking barefoot because flip-flops provide a layer of insulation between your feet and the scorching sand, reducing direct heat exposure. They also protect your feet from potential sharp objects like shells or rocks. Additionally, flip-flops can help prevent burns and discomfort associated with hot surfaces, allowing you to enjoy your time at the beach more comfortably.
