Attipas Acti-Fit Insoles are designed to even out your child's posture and musculoskeletal system from head to toe. When your child's posture is aligned, they can actively live a better and healthier life. Misalignment of knees and joints are often a result of hyperpronation, which occurs when ankles roll excessively during standing, walking or running. When untreated, hyperpronation can cause aches, chronic pain, and injury. Attipas Acti-Fit reduce the risk of hyperpronation in babies and toddlers.
