For $2.49 its hard to go wrong but these have one major serious design flaw. the little plastic ends that keep the laces together come off very easily. When that happens the inner and outer lace separates and ends up creating a tangled mess of laces.  Since I don't sine any viable alternatives here on Amazon my solution, instead of buying a different brand, has been to staple the ends on as soon as I get the laces. The little plastic ends still fall off but at least with a staple through the lace (which no one can really see, the inner and outer lace still stays together.
