The PowerStep® Heat Moldable shoe insoles were designed to provide a personalized, custom fit for all arch types through heat-molding technology. The PowerStep Heat Moldable full length insoles have a unique design with two layers of plush cushioning and a heat moldable base, allowing for maximum comfort with a customized fit. The anatomical contoured arch support and heel cradle stabilize the foot and improve alignment, adding stability and motion control to limit excess stress on feet, ankles, joints, and tendons. The Heat Moldable insoles provide the perfect blend of stability and cushioning for any arch type. HOW TO GET A CUSTOMIZED FIT: 1. Loosen shoes and remove all padding/factory insoles. 2. Preheat your oven to 225° F. 3. Bake one insole at a time until the white heat sensitive paper tab on the bottom of the insole turns black (approximately 1 min 30 sec). DO NOT OVERHEAT Quickly remove insole from oven and place into shoe. While wearing socks, insert foot into shoe. Stand on insole with knees slightly bent for 1 min. DESIGNED FOR EVERYDAY USE: PowerStep Heat Moldable insoles are made to fit sized, meaning no trimming, you order your shoe size. Inserts are movable from shoe to shoe if necessary and are intended for footwear where the factory insoles can be removed. First time PowerStep or orthotic insert users may need a transition period of wearing insoles only a few hours a day until feet are accustomed to all day support and stability.
