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.  Mens shoe sizes: S(5-6.5), M(7-8.5), L(9-10.5), XL(11-12), XXL(13-14).  Womens shoe sizes: S(6-7.5), M(8-9.5), L(10-11).
