PowerStep Pinnacle 3/4 insoles made of a royal blue polyester top fabric with pattern and black foam layer cushioning. It features grey external semi-rigid polypropylene support shell arch and black anti-slip vinyl with rubberized textured surface pad. These insoles with built-in neutral arch support and plush cushioning foam layer are the perfect balance of comfort and support in an even lower profile design. It's 3/4 length with tapered edge leaves extra room at the toes while the non-slip pad at the heel helps hold the orthotic in place. The insoles feature the signature PowerStep arch shape but with a low, flat heel cradle 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 3/4 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 that does not have a removable factory footbed and designed for shoes with less depth at the toes such as athletic (walking/running), casual & dress. 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.
