My laces are always too long and IO can't stand the sound of them flapping on the sneaker. They also seem to always loosen, so I decided to try these. I thought it was a little on the expensive side, but the fact that they are not permanent and I can put them on other sneakers when the sneaker wears out, or I want to switch sneakers for a time, that is great.
Black is the perfect color, because pretty much every sneaker I have is black. I even wear black sneakers for work because my feet can't handle and dress shoes. Being that they are black, they don't stand out and cause any double takes.
They are plenty long so you don't have to worry about running out of lace. I left  2-3 inches just like the instructions said. I cut off 6 inches.
