How to use: Just lace up these running shoes and you're ready to hit the road. They're great for your regular running workouts. Note: Make sure to choose the right size for a comfortable fit. If your feet swell during long runs, you might want to go a half - size up. Maintenance: After each run, take out the insoles and let the shoes air dry. Don't put them in the dryer as it can damage the materials. Clean the shoes with a soft brush and mild soap when they get dirty.
