Shoe laces evolve? Yes, they do, and our friends at Nathan Sports have released their new LOCK LACE. These next generation shoe laces are made for athletes. They stretch to fit comfortably; they adjust and lock-in better; they can be done and undone faster for transitions; they are water resistant and once size fits all. Hey, if Velcro can put zippers on the defense, then the LOCK LACE may just do that as well for our old fashioned shoe laces.
