Shoe inserts help absorb moisture so your feet don’t slip and shoes stay drier longer. Inserts that come in one size may be trimmed down to fit your shoe. Wear inserts designed to absorb sweat when not wearing socks with shoes. If the inserts are not washable, replace as needed. Nonstick insoles are easy to remove and may be used in different pairs of shoes.
Many shoe inserts have a washable fabric layer, but they are not machine washable because other parts of the insert, such as gel padding, may become damaged in the machine. These types of inserts may be handwashed in soap and warm water. There are washable terrycloth insoles available on the market. They are soft on bare feet and absorb moisture. These insoles are typically padded with latex for added comfort and perforated to allow air to circulate in the footbed.
Thin, ventilated fabric insoles with activated charcoal and baking soda are made to absorb sweat and fight odor-causing bacteria and fungus. A durable foam bottom provides added comfort and support. Other types of odor-fighting inserts are made of a moisture-wicking fabric to keep feet dry. Some have a silver-based antimicrobial layer that wards off bacteria to fight odor.
Memory foam inserts conform to the shape of your foot for personalized comfort and support. The foam inserts also provide shock absorption to help prevent achy legs and feet, especially when worn while standing or walking for long periods at a time.
Orthotic shoe inserts are molded to provide extra arch support and shock absorption. It is recommended that these inserts be worn while exercising, playing sports and running for added protection. Orthotic insoles help the feet properly aligned to prevent aches and repetitive stress injury. Some brands of orthotics come with antimicrobial properties which are preferential if wearing with bare feet. Orthotics may be purchased via a podiatrist, and less expensive options are available over the counter.
