Trim To Fit
If you need to trim the length of your new insoles, do so ONLY along the toe area. Use your old insoles as a guide; place your old insoles on top of your new insoles and align the heels. Mark a line onto your new insoles showing any extra toe area that extends beyond the old insole. Carefully trim using sharp scissors
Cleaning
You can hand wash New Balance insoles with New Balance's Gel Cleaner Deodorizer or use a soft scrub brush and mild detergent, then rinse well and air dry completely before reinserting into shoes
