Hi Joan, I've tried the inserts both inside and outside my brace. I've also tried having 1 inside and 1 outside at the same time. What I've found works best for me is one on the inside of the sneaker. It does take time however to break in a new pair of sneakers. When I get new ones I wear the insert on both the inside of the brace and the sneaker. Once I get used to the new sneaker I can remove the one in t Hohe brace.Hope this can work for you as well...please let me know...Jeannie
