I'm a Biochemistry research scientist, which means 2 relevant things to this review.  First, I'm on my feet a LOT and second, I am required by law to wear closed toe shoes every day, all year round.  That means I own/wear a lot of casual shoes and sneakers that lace up and are constantly coming untied.  I also have a 6 year old son with autism who does "do" shoes with laces.  This is a wonderful and effective product that has made a difference in our lives!  I have now converted two pairs of my own shoes (a pair of Vans and a pair of Taos sneakers) with these laces and have loved it so much that I plan to finally buy my son some non-velcro shoes and convert them to slip-ons using these as well!  They really are pretty easy to install (if you watch the instructional video and follow along) and work perfectly so far!  My shoes are now easy to slip on, super comfortable and I don't have to worry about big ugly bows or my shoes coming untied!  They're the perfect fit every time!  You can choose the hidden method or the pieces that lock the laces on top of the shoe.  I go hidden mode every time.  The little lace anchor fits between the tongue and the eyelets and I can't even feel it when I put the shoes on.

If I had two complaints, the first would be that they don't come in a cream or off white color.  They actually have a great color section but I was really hoping for that specific color.  Second, these laces look very much like they're meant for athletic shoes, which they probably are, but I'm using them on casual shoes as well and it would be nice if they had some that were wider/thicker and looked more like casual shoe laces rather than really thin  "sport" laces if that makes sense.  Still, I'm very very happy that I found these and will definitely recommend them to everyone I know!  I paid full price for these (which I thought was very fair) and have no affiliation with this company whatsoever.
