Crocs Crocband Mammoth, a twist on the original, has furry fleece lining that keeps your feet toasty without giving up the essential style, comfort and flexibility from Crocs. Crocs Crocband Mammoth has a higher heel and a sporty midsole band inspired by the classic vulcanised clog style. The lightweight, slip resistant Crocs Crocband Mammoth in this popular winter version has an adjustable heel strap that can be worn up or down.
