Heat treated customizable insoles. To mold the insoles to your feet, Vittoria recommends using an oven set to 200 degrees. Simply place the insoles on a cookie sheet for 2 minutes. After 2 minutes remove the insoles and put them in your shoes. They recommend doing it quickly because the insoles can harden within 45 seconds. Once in your shoes, put on both shoes and stand in them for about 3 minutes. After that the insoles should be custom to your feet.
Note: You should be wearing socks when performing the molding procedure.
