There’s a big difference in the various types of superfeet… Also, pain in the insteps is a different problem than having pain under your toes/ ball of foot.
If you’re having pain in your instep, you might be using a version with too big of an arch support (i.e. the green ones). Try the blue or orange. (or, I think purple for women are equivalent to orange… but not sure).
If you’re having pain under your toes or the ball of your feet, this can be due to the lack of padding in the ball area of some superfeet varieties. The newer orange superfeet have padding in the toe area, and for me are the perfect choice. If you already have some other ones, you can try to put a thin liner under the superfeet - sometimes even the shoe’s original insole can work… just keep in mind that it might reduce the overall space available in your shoe, which can cause other problems.
If you’ve tried a couple varieties and had no luck, you might try something else.
