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 optimally surrounds your heel. This provides the necessary support for the foot and automatically encourages the correct posture. An improved fit and grip in the shoe enhance stability and walking safety. Sizes: A: 32 - 34, B: 35 - 37, C: 37 - 39, D: 40 - 42, E: 43 - 45, F: 45 - 47, G: 48 - 50.
