One of SuperFeet's first and most-loved inserts, GREEN delivers professional-grade orthotic support, performance and comfort for anyone who wants their footwear to fit and feel better. Responsive closed-cell foam provides a firm foundation for lasting comfort, and the high-profile shape fills the entire width and length of your shoe for maximum support. The wide and deep heel cup is sculpted for added cushioning and pain relief, while the high arch support provides stabilization to reduce stress on your feet, ankles, knees and back. Engineered to keep their shape, GREEN insoles deliver reliable performance for up to 12 months or 500 miles, whichever comes first.
