Using the Caterpy Run 2.0 Lace is easy. Just thread them through your shoe eyelets like regular laces. Tie the knot as you normally would, and the anti - slip feature will keep it in place. For best results, make sure the laces are evenly tightened across the foot. When it comes to maintenance, you can easily wash them by hand with mild soap and water. Let them air dry. As for precautions, avoid using sharp objects near the laces to prevent damage. Also, don't over - stretch the elastic part, as it might affect the fit and performance of the laces.
