Fit Flop's über-popular super-cozy leather Mukluk boot is a little bit tougher, a wee bit more waterproof, & possibly more practical than its fuzzier forerunner. With natural sheepskin lining, & an ergonomically engineered, triple-density cushy Microwobbleboard™ midsole. (If it’s a toss up between classic or leather, just take the two!)
