These three-layer insoles begin with a durable, anti-microbial pad that wicks away moisture and refuses to emit odor. It sits atop a 4mm high density moldable foam that quickly takes on your foot shape. Below that, we've incorporated a firm, supportive base layer to keep your arch and heel stable... and you on your feet all day long. Imported.
