Superfeet insoles were developed in the United States. They are designed to ensure the foot's neutral position (normal position) and allow the foot to function correctly. The main feature is that instead of directly compressing the arch, the structure supports the arch with a sturdy heel cup. This structure allows your own arch to function as a cushion, and the fat on your heel also acts as a cushion. My impression after using them is that the perfectly fitting heel cup feels good, as if it's gripping the heel, and there's no sensation of the arch being lifted. There's a feeling of being lifted on the inside of the heel, and the arch of the foot feels supported in that area. Since there are different depths of heel cups, if you use them according to the height of your arch, even people who don't like arch-lifting insoles can use them with less discomfort. Please check the official website for details. Used once. I think it's in relatively good condition. Cut to 26cm. Please purchase if you understand that this is a used item. No returns or refunds.
