Improve your posture with the brand new orthopedic Posture insoles 3/4. Posture starts with the feet. 70-80% of people have an incorrect foot position - the foot leans either inward or outward. Incorrect foot position affects the ankle, knee and hip and can cause pain, injury or impaired posture. Posture Insoles 3/4 are designed to stabilize foot position and support natural walking style. By bringing the foot, ankle, knee and hip into proper position, posture is improved. In addition, the insoles can prevent rotations that lead to stress injuries and compromise posture. Suitable for everyday use in all types of shoes.
