There are running shoes that stay tied and there are others that don’t. If you are a runner, I’m sure you know the scenario. You're happily running along, enjoying the trail and the scenery and then you feel a loosening of your favorite running shoes.
Sometimes, it takes a running friend to tell me that my laces are starting to unravel. This means I need to stop, retie my laces and hope they will stay tied for the rest of the run. Even when I double-knot some laces, they still manage to find a way to come untied mid-run. It’s even more annoying when laces loosen while running a race, because it means I lose valuable seconds or minutes stopping to tie my footwear again.
