Ideal for those with low to neutral arch types, the Sof Sole Airr Orthotic Performance Insole is designed to enhance motion control and support. A Skydex encapsulated air chamber in the heel converts impact into kinetic energy, while polymer gel in the forefoot delivers even greater shock absorption. The Coolmax top cover wicks away moisture to keep feet cool and dry, while a Microban antimicrobial treatment helps prevent the growth of odor-causing bacteria so feet stay fresher longer. A nylon stability plate in the arch and heel reinforces foot alignment for maximum comfort. Imported.
