Orthopedic insole specifically designed for tight-fitting shoes. Sneakers and everyday shoes often provide little space for an alternative insole due to their cut. The SuperfeetGrid® Blue fills this gap and offers excellent cushioning properties. The patented heel cup from Superfeet perfectly surrounds your heel, providing the necessary support and helping your foot automatically adopt the correct posture. An improved fit and hold in the shoe enhance stability and also increase traction. Sizes: A: 32 - 34, B: 35 - 37, C: 37 - 39, D: 40 - 42, E: 43 - 45, F: 45 - 47, G: 48 - 50.
