Reef's Honey-Do Slipper ($36) is the very definition of cozy footwear. If you're not convinced by it's cushy looks, know that it's made with super-soft sherpa lining which make it one of the most comfortable slip-ons that you can, well, slip in. The inviting foot bed also has anatomically-correct arch support. It comes in various sizes and in two styles - corduroy and plaid.
