Sandals are a type of footwear that typically have an open design, with straps or bands that secure the foot to the sole. They can be made from a variety of materials, including leather, synthetic materials, and rubber. Sandals can range from casual, flat styles that are great for everyday wear, to more formal, heeled styles that are appropriate for dressier occasions. There are many different styles of sandals, including flip-flops, slides, thong sandals, gladiator sandals, and more. They are often a popular choice for warm-weather footwear, as they provide excellent ventilation and allow the feet to breathe.
