These plush, therapeutic "slippers" are lined with a unique Gel that gradually releases moisturizing oils that soothe rough, dry, cracked skin and soften feet fast. After just a few wearings -- overnight or around the house -- feet feel soft and smooth, cracks start to disappear, corns & calluses shrink. Apply moisturizing creams to feet before use for even faster results. Non-slip soles. Washable, reusable and effective for months.
