You will need:
Small diameter heat shrink tubing
Hot air gun or similar heat source
Super (Krazy) glue
Most hardware stores carry heat shrink tubing, but in black only. If you want your aglets (that’s what the ends of your shoelaces are called) to remain clear, or white you will have to spend a few extra bucks and get an assorted pack from Radio Shack. The part number is 278-1610
. The assorted pack will provide you with a lifetime supply of tubing for shoe lace shortening.
