As the temperature heats up shoes become harder and harder on your feet. Unlike the rest of you, your feet are trapped in an enclosed area for hours upon hours throughout the day. On days that are already hot, the heat of the shoes is amplified because the shoe locks the heat inside. Hot shoes equal sweaty feet, which then can lead to odors. Keep your feet from smelling up the room and let them get some air with open shoes like sandals or flip flop.
