Once on they fit comfortable in my ear & work great! I was never happy with the slides for one reason or another, until I found these slides. I liked the cd. They are still comfortable after wearing them for long hours during the day. They are pretty cushy and for a job that you are on your feet all day they are decent. Wonderful for game. Also, I must state that I have been using my waist trainer in addition to my workouts and NOT a substitute for it which is probably why I have had such success with it. Wanted something that was as comfortable as a sneaker but with a dressier look. Even though this does not have anything to do with it I was born with a rare skin condition in every material makes me itch that I work out and. I love my bike now stands straight up and down.
