Paracord Shoe Grips

My girlfriend is absolutely petrified to walk on snow and ice.  We had to go someplace so I needed a solution that I could use now without going to buy anything. I had a little para-cord laying around so I created this.  I was inspired by yaktrax to create this idea.  People have been using rope on the bottom of their shoes for centuries and the nylon used to make para-cord sticks to wet snow and ice.

As with most ideas this one is rather simple, first you find the halfway point of your cord.  You then make a loop using what I think of as a half figure eight knot.  You can use a full figure eight knot as well.  You then put the loop over the toe with the knot facing down.  

Wrap the cord around the back of the shoe and thread it threw the laces to keep it tight and from falling off of the shoe.  

Take the cord over the toe of the shoe keeping it tight and make another knot before bringing it back up to tie it around threw the laces.  Keep the cord as tight as possible so that it does not slip off of the shoe.
