Our shape. We use cutting-edge technology and innovative materials to take elements of our proprietary Superfeet shape and create insoles tailored to specific activities, uses and footwear styles. Some Superfeet insoles may feel different than you expected. This design is intentional — the contours of each insole are positioned to have maximum impact on the way your foot functions as you move. However, your comfort is key — if the insole feels uncomfortable to you, try a different Superfeet style.
