The SofComfort Extra Support Plus Heavy insole is made to support men over 200 lbs. The insole has an arch plate and foam impact zone for added comfort. May be trimmed as needed for a true custom fit. To trim, simply remove the existing insole from your shoe, line it up with your new insole as a guide and trace with a ballpoint pen. Carefully cut with a sharp pair of scissors, then insert into your shoe with the top side up. A perfect addition to your everyday work boot. Fits men's size 8-14.
