Insoles made with materials such as cork, gel, or breathable foam are often a good choice for summer.
These materials can help wick away moisture and keep your feet cool and dry in hot weather. In addition, you may want to look for insoles that have perforations or other ventilation features to allow for maximum airflow. Some brands also offer antimicrobial insoles, which can help prevent odors caused by sweat and bacteria.
Ultimately, the best insoles for summer will depend on your specific needs and preferences, as well as the types of shoes you’ll be wearing them in.
