These and the original inserts are still life-changing! I can wear almost any height of heel now with these in and have no problem! I also use these in my slim tennis shoes. TO KEEP THEM FROM SLIDING in heels, I put industrial strength velcro on the bottom of these inserts and the opposite side in the bottom of my shoes. I have no problem now with them sliding! I use double-sided tape for the original and cloud inserts when needed, but it does not work long for these inserts.
