Dr. Scholl's Heavy Duty Support Insoles are scientifically designed and engineered for men who suffer from lower back pain and leg fatigue and are either over 200 pounds, tall or have wide feet. These durable insoles with extra cushioning surrounding the heel are clinically proven to help reduce lower back pain and leg fatigue. Providing all-day support and relief, every day! How To Use: Your shoe's current insoles may be removable, if they are take them out FIRST. Place the removable insoles against the back of your Dr. Scholl's insole and trim to match the old insole size. If your shoes' insoles aren't removable, cut to your shoe size using the trim guide found on the bottom of your insole near the toes. Place insoles in your shoes, toes first with the cloth side UP. Ensure the insole heel rests firmly in the heel of your shoe. Recommend replacing insoles every six (6) months or at first sign of wear. Why It Works: Lower back pain and foot and leg fatigue can result from the everyday pounding your feet take during daily activities such as standing and walking. This problem can be particularly a for men over 200 lbs.
