A 'comfort fit' ring is a ring that has an oval cross-section. In most cases a ring has a flat interior or an interior that's ajouled out, which means hollowed out. A 'comfort fit' ring is not that way. In fact, its contour is opposite of the flat ring. The benefit of having a 'comfort fit' ring is that over time, it doesn't wear away, whereas a ring that has a flat interior tends to wear and may have some sharp edges occur over time.
