Yes, in most, but not all cases. The Superfeet Insoles will help hold the rearfoot close to a neutral position. The neutral position will allow for better bone and muscle alignment. This will help reduce some of the stress on the plantar fascia ligament.
Clean the Superfeet Insoles on a regular basis (twice a week).
Remove the Superfeet Insoles from your shoes every night to let the shoes and Superfeet Insoles air out.
Do not wear the same pair of shoes three days in a row.
Try different brands of socks or nylons.
Apply a teaspoon of baby powder under and on top of the footbed in the shoe.
Apply some scented hand or body lotion to your feet.
Try soaking your feet in warm water and Epsom salts for about 20 minutes, once or twice a week.
We do not recommend that you place a Superfeet on top of the manufacturer's sock liner (insole). However there are shoes where the factory insole may not be removable. You may place the Superfeet in these shoes as long as it doesn't make the fit of the shoe too tight against your foot. The best Superfeet insole option for shoes without removable insoles is the 3/4 Easy Fit model.
If the Superfeet insoles are new and make a squeaking sound, there could be a number of causes.
Give the product two weeks to mold to your feet and settle into the shoe. The sound generally dissipates. If after this time the squeak is still there, apply some baby powder inside the shoes under the insoles and apply some baby powder on the bottom of the plastic Superfeet cap. You can also try the insoles in different shoes to see if this squeak goes away. Check to make sure that the product is not trimmed too long for the shoe's internal length. Jamming the insole in the shoe can create problems with fit and function.
When you first try on the Superfeet product you may feel like the arch is too far back. This is not uncommon and it can be a positive feedback from the product. All Superfeet products are primarily designed for feet that over-pronate. If you feel like the arch is too far back, the product is actually telling you that it's trying to support you rear foot (heel bone) so the foot doesn't have the ability to collapse. As you go through the break-in period with the product, it may take 10 minutes to 2 weeks for the feeling of the high spot support to dissipate. If the feeling does not dissipate and become more comfortable, contact the Superfeet dealer where you purchased the product or call customer care to help you determine if you have purchased the correct size for your foot and the correct model for the shoe style and your foot type. If you trim the Superfeet insole too long for the shoe, it will jam the Superfeet in the shoe and give you the feeling that the arch is too far back. You may want to trim the front end of the Superfeet insole so that the product can move in the shoe from front to back, about the thickness of a nickel. This allows the product to be independent of the shoe. The Superfeet product will center itself underneath the foot, increasing comfort and function.
