I purchased 3 brands of hidden cotton liners to see which I would like the best. These were middle of the pack. They stayed on pretty well with some slippage, so for that I can't give it five stars. However, I would give them 5 stars for actually being hidden. They are very low profile and can't be seen when worn with my flats. I should say that the ones I found most comfortable, in that they didn't slide around, could hardly be considered "hidden" as they come up high around the top and back of the foot (which, of course, is why they stay on better). So, if I'm going for comfort and I don't care what it looks like, I wear those, but if no-show is most important I definitely reach for these. Other than needing to adjust them periodically, they do just fine. I would recommend if no-show is your #1 priority. Overall, I think Hue generally makes a pretty decent product.
