Here's a little tweak on the traditional way most people tie shoes. The result is a knot that holds up better, comes untied less often, but can still be untied very easily. The knot is also easy enough for kids to learn, so parents can spend less time tying and re-tying their kids' shoes.
Once you try this knot, you will never go back to the old way of tying your shoes.
Thanks to Lifehacker.com for bringing this knot to my attention.
