I have tried with paracord, it is stretch but it will work, nontheless. We could also soak the paracord in water and let it dry to make it less stretchy.
It's a good idea to replace your shoelaces with paracord. In an emergency, you'll always have some with you. If you need it, you can just take out the inner strands so you can still tie your shoes. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
