These are extremely comfortable, warm, good fitting slippers! They have plenty of padding in the bottom so you don't feel like you're walking barefoot with just a piece of fabric wrapped around your feet! The elastic "v" insert on the instep makes for a snug (but not tight) fit (I've had other slippers and within a couple of weeks, they're too loose and don't fit well). They have enough flex in them to be safe going up/down steps, both interior and exterior (with cats twining around your ankles!). I highly recommend these as a nice thank-goodness-I'm-home-it's-been-a-long-day slipper!
