Formerly called the Cayman, the Classic is a slimmed down version of the original Crocs. Perfect, airy, warm weather design that comes in full sizes and is made with croslite PCCR material. Slip-resistant and non-marking soles. Crocs are designed to fit loosely. The wide, roomy footbed may feel large at first, however this is one of the key reasons your Crocs are so comfortable. To adjust the fit, simply stretch the back of the heel strap slowly until it retains the desired length. Odor resistant. Crocs will respond to body heat by molding to fit your feet.
