PowerStep Pinnacle Memory Foam insoles made of a royal blue odor control polyester top fabric that helps reduce heat, friction, and perspiration with pattern and semi-rigid polypropylene support shell arch. It features dual layer cushioning which is lime green ShockAbsorb premium memory foam top layer for those with sensitive feet and royal blue EVA base. These full length insoles with built-in neutral arch support and two layers of plush cushioning are the perfect balance of comfort and support. The plush memory foam layer is a slow-recovery foam that conforms to the shape of the foot for added comfort and pressure relief, alleviating pain associated with fat pad atrophy/degeneration. PowerStep has the signature PowerStep arch shape that cradles the arch and heel, adding stability and motion control to limit excess stress on feet, ankles, joints, and tendons. Feet with neutral arches naturally pronate when walking, where the feet and ankles roll slightly inward, placing pressure on the bigger toes and inside of the foot. Neutral arches need stable, yet flexible arch support for shock absorption and proper alignment. By combining premium cushioning and the clinically proven PowerStep arch shape in a semi-rigid neutral arch support shell, the PowerStep Pinnacle Memory Foam shoe insoles are a trusted solution to improve foot function, decrease arch pain, and help alleviate common foot conditions typically caused by mild to moderate pronation. These insoles are intended for footwear where the factory insoles can be removed and designed for shoes such as athletic (walking/running), work, & casual dress shoes. Proper care: spot clean with mild detergent. Do not immerse in water. Air dry. All sizing is based on US shoe sizes. PowerStep insoles are brand new and 100% authentic.
