Hi Mar, My ankles, heels, and shins were really bothering me from overdoing the step, It was getting so bad after working out I had to put an ice pack on the inside of my ankles! I bought Dr. Scholls sport inserts, the heel cushions only. That solved all of my pain!! It's been about four weeks and no problem. I did notice that if you put them in a loose shoe they slip and slide, but my sneakers fit perfect and they stay put in them. I highly recommend them. Maybe everyone is different and this isn't the solution, but in my case (and I was having alot of pain) it really worked.
Good Luck!
