The Warwick Wedge™ is designed with a 4-degree angle and fits comfortably in the shoe to help alleviate symptoms related to varus (bowlegs) or valgus (knock-knees). By reducing the pronation (rolling in) or supination (rolling out) of the foot, wedge insoles work to relieve pain and stiffness that can be felt in the lower back, legs, ankles and feet due to a misalignment. Reversible design allows it to fit in either the left shoe or the right shoe. Available in three sizes.
