Orthopaedic insole, specially developed for close-fitting shoes. Due to their cut, trainers and everyday shoes usually offer little space for an alternative insole. The SuperfeetGrid® Blue closes this gap and also offers very good cushioning properties. Superfeet's patented heel cap optimally encloses your heel. This provides the foot with the necessary support and automatically adopts the correct posture. Improved fit and support in the shoe increases guidance and sure-footedness for you.
