WEAR MOLD: Place the footbeds into your footwear and wear as with any other shoe. The footbed will wear mold to your unique foot after a few days.
HEAT MOLD: The other option is to heat mold the footbeds in an oven before wearing them. Heat molding will mold the footbeds to your foot instantly, and is recommended for people with very low arches.
Molding the footbeds either way will result in a footbed that matches the shape of your unique foot. The arch and heel cup will adjust to fit you, without flattening out, increasing support and the function of the footbed.
HEAT MOLDING STEPS
STEP 1: Pre-heat the oven. Do not use a microwave.
Conventional oven - Set to bake at 200°F / 90°C.
Convection oven - Start at 175°F / 80°C.
Gas oven - Start at lowest gas mark (1/4, S, SS).
STEP 2: Remove the factory insole from your footwear if possible.
STEP 3: If necessary, trim the footbed to fit. SOLE Custom footbeds should not require trimming to fit in most types of footwear. Please try them in your shoes before doing any trimming. If they do not fit, trim your footbeds to exactly the right size, using your old insole as a guide.
CAUTION: Only trim the toe end and take care not to cut them too short! Fraying of the Thinsulate™ layer may occur when trimming insulated Footbeds (Insulated Ultra, Insulated Response, Signature CD Thin). Some fraying is expected and will not affect the function or integrity of the product.
STEP 4: Place the footbeds directly on the oven rack on a baking sheet for 2 minutes, or until the Opti-therm indicator turns black. If it has not turned black after 3 minutes, remove the footbeds from the oven; they will be ready to mold.
STEP 5: Immediately put the footbeds into your footwear. Ensure they are sitting flat in your shoes and the forefoot is wrinkle-free.
STEP 6: Step into your footwear, and tie up as usual.
STEP 7: Stand up straight with your feet shoulder-width apart, toes pointed forward, and knees slightly bent. Your knees should be positioned directly over the top of your second toe. Maintain this neutral position, ensuring your weight feels evenly distributed across your feet, for 2 minutes.
