Crocs Mammoth Men's Winter Sandals. The furry fleece lining in this Crocs Mammoth clog keeps your feet toasty without giving up the Crocs style. Faux holes on sides nod to crocs original designs, while keeping feet dry for winter wear. A higher heel gives increased protection from winter weather. The Crocs Mammoth is designed for both Men and Women. The sizes listed are in Mens, so to get the correct size in Womens, you will need to add 2 to the size. So if you order a size 6 , when the sandal arrives it will be a Mens 6 / Womens 8. On the bottom of the sandal it should read M6 / W8.
