When the weather starts hotting up, it's time to set your feet free. Sandals are ideal for carefree walks, trips to the beach or chilling at home. Most models feature open toe, middle and heel areas, offer excellent ventilation and are kept on your feet via straps. In addition, specially profiled and non-slip soles provide support when it comes to rough terrain. For home gardening and other to-dos, open-back slip-on models like Crocs are particularly popular.
