I put these New Balance insoles into some New Balance sneakers. While I appreciate the support they provide, there's no way I can sneak up on anyone with the insoles in these sneakers. The two materials of the insole rub to produce a very audible squeak; especially when going up or down stairs. I had to cut them down from size 11 to fit my 10.5 shoes; and they fit well. But may end up going back to the stock inserts because the squeak attracts a bit too much attention.
