The Crocs™ Shoes Mammoth is a strapless slip-on that puts a comfortable twist on Crocs™ Shoes' original designs, keeping feet warm and toasty. Made of Croslite™ material, this shoe features soft, synthetic fur lining that is both removable and washable for easy care. There are false holes on the sides as a nod to Crocs™ Shoes' original design while still keeping feet dry for winter wear, with a coordinating sockliner that matches the shoe and protects the foot from upper holes. A higher heel gives increased protection from winter weather while the loose fit allows feet to bend and expand naturally, reducing fatigue.
