Classic Birks: comfortable, supportive and ready for the long haul. Whether you pair them with a thick wool sweater and jeans or something dressier, they deliver the same flexible shock-absorbing base. Arch support and a deep heel cup cradle you through every step, because feeling good at sunset dance parties never goes out of style. Smooth durable leather uppers. Slip-on style with straps that open if you want. Soft anatomically shaped cork latex core between jute layers for stability and moisture management. Suede leather lining provides a nice climate for your feet. Footbed edge is slightly raised to protect your feet from toe-stubbing. Toe bar guides your toes into place and promotes natural steps. EVA outsole for lightweight durability and absorbing shocks. Smaller sizes (up to 41) come in narrow widths for smaller volume feet.
