I recently received these Dr Scholls inserts from BuzzAgent to review. I wear and collect heels so this was great for me. I really don't use insoles but I decided to try them out on one of my current favorite shoes. What I noticed was that you can't really feel them on. You last more without pain I can usually wear mine for 8 hours but with these I lasted another 1-2 hours. I love that you cant even see them or tell that you are even wearing them. They also help you keep your feet and shoes dry, though they are gel inserts they are not slippery at all and they stay in place.
