Our Slippers are built to the highest standards with extra plush and fleece fibres, one inch thick high density foam inner sole and durable treated outer sole. (not fabric poly-dot like bargain slippers), elastic stretchers at key stress points and reinforced stitching. Some say we have gone too far, after all it's just a novelty slipper - but after 14 years and closing in on a million satisfied customers, we know you will appreciate the quality difference.
