If you're constantly dealing with the issue of flailing untied laces you've got two solutions. #1 Get some retro Velcro shoes, or #2 get some locks for your laces. Lace locks are little plastic bits that keep your shoe- laces contained. That stay put perfectly, come in many different colors, fit all different types of shoes, and will cure the need for double knots once and for all.

Not only are they great for folks sick of pausing a workout to retie their shoes.....they help those who may not have the flexibility to reach their feet. I'm going to get some for my children's shoes as well. Lace locks can be found at running stores and regular sports stores everywhere.
